Installing PHPUnit / Selenium in XAMPP
A small how to install PHPUnit via PEAR in an XAMPP running on a windows box. A prerequisite for a continuous build strategy.
PHPUnit is a member of the xUnit family of testing frameworks and provides both a framework that makes the writing of tests easy as well as the functionality to easily run the tests and analyze their results.
- PHPUnit homepage
- ONLamp.com - Testing PHP Code with PHPUnit
- Planet PHPUnit
- Sebastian Bergmann (creator of PHPUnit)
Installing XAMPP
- Download XAMPP from http://www.apachefriends.org/en/xampp.html
- Unpack the zip, don't run any installer, just use the \xampp\xampp-control.exe to control the component (so the whole XAMPP directory can be moved to another drive without having absolute paths in all configurations files)
Installing PEAR
- Execute \xampp\php\go-pear.bat and follow the onscreen instructions. The installation will modify the include_path in your php.ini file.
- Execute \xampp\php\PEAR_ENV.reg to add PEAR to the windows registry
Installing PHPUnit
- Open a command prompt
- Execute pear channel-discover pear.phpunit.de
- Execute pear install phpunit/PHPUnit
- Now you should find PHPUnit installed in \xampp\php\PEAR\PHPUnit\
Installing Selenium
- Execute
pear install Testing_Selenium

Hackintosh Tutorial: Install a Mac Leopard OS X Retail DVD on a PC
September 4th, 2008 Posted in Hackintosh
After building hackintosh machines using different modified OS X installers, the hackintosh community has come a long way and is within grasp of achieving the holy grail of running Mac OS X on PCs—installing the original, unmodified OS X DVDs created by Apple for Macs on ordinary IBM compatible personal computers. Well, almost.
While we can now use a retail Mac OS X DVD to turn our PC into a hackintosh, we still need a bootloader to get it to recognize and install OS X the first time. The good news is, after a successful installation, we can now install any updates from Apple without breaking our system or reinstall the operating system without having to add the same kexts (drivers) that we already have that makes our non-Mac standard hardware peripherals work.
Pre-requisites
- A PC with Intel Core Processors and Chipset (AMD is not yet supported).
- A Blank CD (for Boot-132).
- A retail Mac OS X DVD Installer (not an Upgrade OS X DVD).
- Download the Leopard 10.5.4 ComboUpdate here.
- Download the Chameleon for Hard Disk here.
- Download the Boot-132 Generic ISO here.
- Download EFIStudio here.
Step 1. Before You Begin
Burn the Boot-132 Generic ISO on a CD. This BootCD should work fine for most hardware configurations; after which, it should be able to install the retail OS X DVD. If this doesn’t work for you, you may need to modify the contents and add the necessary kexts for your hardware. More info here.
Step 2. Install Leopard.
1. Insert your BootCD and boot/start your PC.
2. On the boot prompt, press Enter. You will be asked to enter a two-digit hexadecimal boot device (do not enter anything yet).
3. Remove the BootCD and replace it with the Mac OS X Retail DVD. Wait for the blinking light on your DVD drive to stop and then hit Enter (this will read your DVD drive and not your HD).
Hint: If you keep going back to the bootloader, it only means you don’t have the correct Retail Mac OS X DVD Installer. The best solution is to buy one.
4. Perform the Mac OS X Leopard installation. You may need to use Disk Utility (under the Utilities Menu) to partition and format your HD if you haven’t already. Make sure to select GUID (under Options).
5. Restart after the installation and replace the Retail Mac OS X DVD with the BootCD.
6. On the boot prompt, press Enter. This time, enter the two-digit hexadecimal of the drive where you installed OS X. Enter 80; if it doesn’t show the startup volume of your OS X, hit Esc. Try 81, and so on until you see your OS X volume. Select it and hit Enter.
7. You should now be in Leopard.
Step 3. Update Leopard to 10.5.4
1. Install the 10.5.4 ComboUpdate.
2. Reboot with the BootCD and enter the same two-digit hex you entered before. Select your startup volume and type -v -f (you don’t have to enter these the next time), and press Enter.
3. At this point, you still won’t be able to boot your hackintosh without the BootCD.
Step 4. Install Chameleon
The Chameleon for Hard Disk you downloaded above has the following files:
- Chameleon_DFE_for_Hard_Disk.dmg
- OSX86Tools
- EFIStudio
1. Open Chameleon.
2. Copy the contents of the Extra directory from the Generic.iso CD by dragging it to the Extra Contents folder in Chameleon.
Hint: To do this, you need to perform the following:
- Open the Generic.iso CD from your desktop.
- Double-click on the INITRD.IMG file.
- Double-click on the Extra folder.
- Drag the Extensions folder to the Extra Contents folder in Chameleon
3. Double-click the Chameleon_DFE_for_Hard_Disk.pkg file and install to your hard disk.
4. Remove the BootCD and reboot.
5. You should now be able to boot into Leopard without the BootCD.
Step 5. Fix Your Hardware Peripherals
After upgrading to 10.5.4, some of your hardware peripherals (i.e. video, network card, audio, etc.) may no longer work. Even the kexts that worked for my previous modified OS X installations don’t work with the latest version so I had to scour the net for a fix. Depending on what you have installed on your PC, you may need different solutions. Below are the fixes I applied for my own peripherals.
Network Fix:
Taken from the IONetworkingFamily.kext included in the GA-965P-DS3_ISO bootcd.
Audio Fix:
Taken from the AppleAzaliaAudio.kext included in the Generic.iso BootCD.
Restart/Reboot Fix:
Replace your AppleACPIPlatform.kext with this.
Shutdown Fix:
Download and install this.
Hint: To easily install kexts, you may want to use the OSX86 Tools. Read more about the OSX86 Tool here. You can also use the EFI Studio to try adding EFI Strings to your Boot.plist in case you have problems with video or audio kexts. Read more about EFI here.
Video (Nvidia 7200GS) Fix (QE/CI):
This one gave me the biggest headache. The video kexts or injectors (Nvinject, NvInstaller) that worked for me in the past, no longer works after upgrading to 10.5.4. I tried many versions and none worked. I tried adding device strings to com.apple.Boot.plist using EFIStudio and deleting all video injectors in Extensions and still a no go. I tried to manually edit the kexts by entering my device ID, etc., and still no QE/CI support. Finally, I found out that the Generic.iso BootCD has Nvkush.kext in it and by installing Chameleon, it aslo installed it to my hard drive. So I just deleted it from the /Extra/Extensions folder and made sure I had my video device string in the com.apple.Boot.plist using EFIStudio, reboot and voila!
Now you have a Hackintosh that is as close to a real Mac in terms of the underlying software program. You can safely use Software Update to install updates directly from Apple to your PC.
To get a real Mac experience, buy a Mac!
Những dự đoán ngớ ngẩn nhất trong thế giới công nghệ
Khi nói về tương lai, không ít những “cây đại thụ” về công nghệ cũng đoán sai, thậm chí còn sai bét so với thực tế diễn ra. Dưới đây là tổng kết 7 dự đoán ngớ ngẩn trong lĩnh vực công nghệ 65 năm qua. “Thế giới sẽ chỉ có 5 chiếc máy tính!”
Câu nói “nổi tiếng” này là của Thomas Watson, Chủ tịch IBM năm 1943. Vào buổi bình minh của ngành công nghiệp điện toán, không ai có thể biết chắc chắn rằng công nghệ mới này sẽ đưa con người đi đến đâu. Nhưng sự bùng nổ của máy tính để bàn sau đó đã giúp cho chiếc PC có mặt trên hầu hết các hộ gia đình. Có thể vào thời gian đó, Thomas Watson ngụ ý rằng đó là những chiếc máy tính chạy bằng ống chân không có kích cỡ to như ngôi nhà. Quả thực với một chiếc máy tính khổng lồ như thế thì chẳng có ai lại muốn mang chúng về nhà cả.
“TV sẽ không thể trụ vững trên thị trường”
Năm 1946, Giám đốc xưởng phim 20th Century Fox, Darryl Zanuck nói rằng TV sẽ không thể tồn tại sau 6 tháng kể từ khi nó xuất hiện bởi “mọi người sẽ cảm thấy chán ngắt với chiếc hộp gỗ”. Vào thời điểm đó, 20th Century Fox đã sản xuất được hơn 100 bộ phim lớn trên màn hình bạc. Chính vì thế chẳng có lý do gì để Darryl Zanuck tin rằng những chiếc TV với màn hình bé tí lại sống sót cả.
“Máy hút bụi bằng năng lượng hạt nhân sẽ xuất hiện trong 10 năm tới”
Đó là dự đoán của Alex Lewyt, Chủ tịch công ty Lewyt, được đưa ra năm 1955. Những năm 50 của thế kỷ, chủ đề hạt nhân trở thành “hot” trên mọi phương tiện thông tin đại chúng. Người ta thậm chí còn “choáng hơn” khi Alex Lewyt tuyên bố rằng hãng của ông sẽ nhanh chóng tạo ra chiếc máy hút bụi chạy bằng năng lượng hạt nhân trong khoảng 10 năm, tức là năm 1965. Thực tế đó đã không bao giờ xảy ra bởi năng lượng hạt nhân là lĩnh vực cực kỳ phức tạp, mang tầm cỡ quốc gia chứ không phải là lĩnh vực để các doanh nghiệp nhảy vào.
“Chẳng có lý do gì mà người ta phải dùng máy tính tại nhà”
Câu nói “nổi tiếng” này là của Ken Olsen, sáng lập hãng Digital Equipment Corporation (DEC), năm 1977. Cách đây 10 năm, DEC đã được hãng Compaq mua lại, nhưng vào những năm 70 của thế kỷ, DEC là một tên tuổi lớn trong ngành công nghiệp máy tính. Sau 4 năm kể từ tuyên bố của Ken Olsen, chiếc máy tính đầu tiên của IBM ra mắt đã phần nào đánh đổ giả thuyết này.
“Apple đã chết!”
Thực ra thì đây không phải lời nguyền rủa đầu tiên của các nhân vật chóp bu Microsoft dành cho đối thủ Apple. Nhận định có phần cay độc này là của Nathan Myhrvold, cựu giám đốc công nghệ Microsoft năm 1997.
Công bằng mà nói thì vào thời điểm đó cũng có nhiều yếu tố để Nathan Myhrvold đưa ra nhận định trên. Tuy nhiên, 10 năm sau không những Apple không chết mà còn vươn lên là hãng công nghệ hàng đầu thế giới với những cải tiến và sản phẩm sáng tạo mà không phải hãng này cũng có được. Những sản phẩm đỉnh cao của Apple như máy Mac, iPod, iPhone luôn được cộng đồng người dùng đánh giá cao ở sự sáng tạo, tính nghệ thuật, mức độ hữu dụng và khả năng công nghệ đỉnh cao.
“Hai năm nữa, thư rác sẽ không còn”
Đó là tiên đoán của Chủ tịch Microsoft Bill Gates năm 2004, nhưng thực tế lại trái ngược hoàn toàn. Những thống kê gần đây cho thấy lượng thư rác đã chiếm gần 92% e-mail lưu thông trên toàn cầu. Các biện pháp ngăn chặn thư rác tỏ ra không mấy hữu ích, và bản thân Microsoft cũng chưa có giải pháp hữu hiệu nào cho việc này. Nói vậy để biết rằng không phải dự đoán nào của một người được coi là nhân tài như Bill Gates cũng trở thành hiện thực.

9 Promising PHP Template Engines
PHP template engines are used widely to seperate the code & the layout.
It sure has some drawbacks which is generally the performance (most libraries offer great solutions there) & need to learn a new syntax (not always).
To mention, using a template engine may not be suitable for every project. A website with few pages will probably won’t need it. But it can improve the development process of a portal, an e-commerce site or another web application easily.
Here are 19 PHP template engines with very nice features & have a continious development:
Smarty
The most popular PHP templating engine which prefers to call itself a "template/presentation framework" as it equips both the designer & programmers with powerful tools at the presentation layer.
It has a robust caching mechanism as well as a strong plug-in & add-on support.
With the template functions, debugging capabilities, security it provides & continious development, Smarty is a great engine.
Dwoo
Dwoo aims to be a serious alternative to Smarty with a cleaner codebase.
It has almost a totally compatible template & plugin system with Smarty.
Some main features are:
- Template Inheritance, a fresh look at complex template structures, now built without includes.
- Flexible plugin creation.
- Scope aware engine, allowing for shorter templates.
- Unicode / UTF-8 support for string manipulation functions & more..
Savant
A lightweight templating engine for PHP.
it uses PHP itself as its template language & no need to learn a new markup system.
Template Blocks
Template Blocks is a visual template engine, replacing any semantics of previous generation engines with an AJAX interface.
The engine is lightweight, flexible & extensible.
You can give any section with static content any extension of these popular extensions you like: .html, .htm or .php. They will all load up the same content!
Open Power Template
The new Open Power Template contains a built-in XML parser that fully understands the structure of your HTML code. It can find unclosed tags and perform complex operations on its structure.
For a better performance, every template is compiled into the PHP code, so that its execution is fast and can be speeded with the PHP accelerators. And results are cached.
TinyButStrong
A very easy to learn & implement templating system.
It is only 1 file, 1 PHP class with 6 methods & 5 properties.
Simplicity is its power. It can connect to any database, has a caching system & provides easy date-time and numeric formats.
Rain TPL
An easy to use and install engine which has 6 tags, 3 PHP functions and 2 PHP classes.
Rain TPL is WYSIWYG friendly, you can work with img/css relative paths & they are converted to the correct server path.
PHPTAL
PHPTAL is a PHP implementation of ZPT. To be short, PHPTAL is a XML/XHTML template library for PHP.
While most web developpers continue to use PHP tags as the core language of their templates, the Zope community came with a refreshing idea named TAL which is moving presentation actions inside XHTML attributes instead of using plain tags or elements.
PHP Template Engine
This PHP templating engine uses PHP, not a template scripting language.
It has a straightforward user authentication, session & cookie system. There is a built-in support for MySQL connections & your own classes/functions can be added with ease.
Template Lite
Template Lite, previously known as Smarty Light, is a drop in replacement for Smarty.
It supports most of the features of Smarty. Also, mentioned to be faster & consumes less memory compared to Smarty.
VTE - Vivvo Template Engine
VTE, originally built for Vivvo CMS but distributed for free, is light-weight, easy to use, yet powerful and scalable.
The template engine that can do recursions, object calls, arrays, but still remain within a single class in less than 1000 lines of code!
VTE language is XML-based and it consists of tags and attributes.
XTemplate
XTemplate allows you to store your HTML code separately from your PHP code.
It has many useful features yet code is short, highly optimized & used in various commercial & open source projects.
vlibTemplate
vlibTemplate is a class for templating PHP applications. It is normally included in the vlib package which has the following 3 classes:
- vlibTemplate
- vlibDate
- vlibMimeMail
Using this class you set the values for the variables, loops, if statements, etc. which are declared in the template. This enables you to separate all of the design from the data, which you create using PHP.
PHP-Sugar
It has a similar spirit with Smarty.
A flexible compilation engine that allows expressions similar to that of PHP itself is used. It also has a clean and easy to understand syntax.
Output is HTML-escaped by default, instead of requiring explicit escaping like PHP itself, which makes it far less likely to accidentally introduce an HTML or JavaScript code injection vulnerability from user-submitted content.
FXL Template
FXL Template an easy to use template engine covering all the basic features of a template system.
It supports:
- simple text/array assignments
- blocks
- nested blocks.
The template markup is really easy to learn & for high traffic enviroments a "memcached" cache extension exists.
Blitz templates
Blitz templates is a fast template engine written in C and compiled as a PHP module.
It started as a php_templates replacement, but developed into much more. It is based on extensible template controllers (PHP) and weakly-active templates (HTML).
Vemplator
With 220 lines of code, Vemplator offers:
- Conditionals: if/else and switch statements
- Dot-notation for class member variables (customer.name)
- Associative and numerical arrays (row[0] and rows[1]['name'])
- For-each looping over arrays (associative and numerically indexed)
- Includes (included templates are parsed and cached separately)
Template Engines Under PEAR
4 PEAR packages on templating:
QuickSkin
QuickSkin, previously known as SmartTemplate, works like a ‘template compiler’ that converts templates into executable PHP code and stores it for later reuse.
It supports:
- Simple Scalar Substitution (Strings, etc.)
- Block Iterations (nested Arrays / BEGIN..END)
- Basic Control Structures (IF..ELSEIF..ELSE)
- Custom Extension (Output filters, uppercase, sprintf, etc.)
- Template Compilation (HTML templates are converted to executable PHP Code)
- Output Caching (Accelerates your applications by reusing page output)
What is your preference of PHP template engines & why?

PHP regular expressions examples
Mastering Regular Expressions
Mastering Regular Expressions quickly covers the basics of regular-expression syntax, then delves into the mechanics of expression-processing, common pitfalls, performance issues, and implementation-specific differences. Written in an engaging style and sprinkled with solutions to complex real-world problems, MRE offers a wealth information that you use. I will start with some simple usage examples of the regular expressions and continue with a huge list of cases for various situations where we would normally need a regex to operate. We will use simple functions which return TRUE or FALSE. $regex will serve as our regular expression to match against and $text will be our text (pretty obvious):
function do_reg($text, $regex)
{
if (preg_match($regex, $text)) {
return TRUE;
}
else {
return FALSE;
}
}
The next function will get the part of a given string ($text) matched by the regex ($regex) using a group srorage ($regs). By changing the $regs[0] to $regs[1] we can use a capturing group (in this case griup 1) to match against. The capturing group can also have a name ($regs['groupname']):
function do_reg($text, $regex, $regs)
{
if (preg_match($regex, $text, $regs)) {
$result = $regs[0];
}
else {
$result = "";
}
return $result;
}
The following function will return an array of all regex matches in a given string ($text):
function do_reg($text, $regex)
{
preg_match_all($regex, $text, $result, PREG_PATTERN_ORDER);
return $result = $result[0];
}
Next we can iterate (loop) over all matches in a string ($text) and output the results:
function do_reg($text, $regex)
{
preg_match_all($regex, $text, $result, PREG_PATTERN_ORDER);
for ($i = 0; $i < count($result[0]); $i++) {
$result[0][$i];
}
}
Extending the above one we can iterate over all matches ($text) and capture groups in a string ($text):
function do_reg($text, $regex)
{
preg_match_all($regex, $text, $result, PREG_SET_ORDER);
for ($matchi = 0; $matchi < count($result); $matchi++) {
for ($backrefi = 0; $backrefi < count($result[$matchi]); $backrefi++) {
$result[$matchi][$backrefi];
}
}
}
}

Mastering Regular Expressions quickly covers the basics of regular-expression syntax, then delves into the mechanics of expression-processing, common pitfalls, performance issues, and implementation-specific differences. Written in an engaging style and sprinkled with solutions to complex real-world problems, MRE offers a wealth information that you use. I will start with some simple usage examples of the regular expressions and continue with a huge list of cases for various situations where we would normally need a regex to operate. We will use simple functions which return TRUE or FALSE. $regex will serve as our regular expression to match against and $text will be our text (pretty obvious):
function do_reg($text, $regex)
{
if (preg_match($regex, $text)) {
return TRUE;
}
else {
return FALSE;
}
}
The next function will get the part of a given string ($text) matched by the regex ($regex) using a group srorage ($regs). By changing the $regs[0] to $regs[1] we can use a capturing group (in this case griup 1) to match against. The capturing group can also have a name ($regs['groupname']):
function do_reg($text, $regex, $regs)
{
if (preg_match($regex, $text, $regs)) {
$result = $regs[0];
}
else {
$result = "";
}
return $result;
}
The following function will return an array of all regex matches in a given string ($text):
function do_reg($text, $regex)
{
preg_match_all($regex, $text, $result, PREG_PATTERN_ORDER);
return $result = $result[0];
}
Next we can iterate (loop) over all matches in a string ($text) and output the results:
function do_reg($text, $regex)
{
preg_match_all($regex, $text, $result, PREG_PATTERN_ORDER);
for ($i = 0; $i < count($result[0]); $i++) {
$result[0][$i];
}
}
Extending the above one we can iterate over all matches ($text) and capture groups in a string ($text):
function do_reg($text, $regex)
{
preg_match_all($regex, $text, $result, PREG_SET_ORDER);
for ($matchi = 0; $matchi < count($result); $matchi++) {
for ($backrefi = 0; $backrefi < count($result[$matchi]); $backrefi++) {
$result[$matchi][$backrefi];
}
}
}
}

Decorators with Zend_Form
LINK
Zend_Form has been lauded by many as a welcome addition to Zend Framework, and a flexible solution to the problem of forms. That said, one point of flexibility it offers has proved to be a pain point for many developers: decorators. This tutorial aims to shed some light on decorators, as well as provide strategies for creating your own decorators and combining them in creative ways to customize the output your forms generate.
How to use Zend_Log
Setup the logger in the Bootstrap file:
//initiate the logger - Log to a file
$writer = new Zend_Log_Writer_Stream($root.'\log\test.txt');
$logger = new Zend_Log($writer);
//Log to Database.
$columnMap = array('lvl' => 'priority', 'msg' => 'message', 'timestamp' => 'timestamp', 'lvlName' => 'priorityName');
$dbwriter = new Zend_Log_Writer_Db($db, 'log_table_name', $columnMap);
$logger->addWriter($dbwriter);
//Log to firebug
$writerFirebug = new Zend_Log_Writer_Firebug();
$writerFirebug->setPriorityStyle(6, 'TRACE');
$logger->addWriter($writerFirebug);
$registry->logger = $logger;
Using the logger:
$logger = Zend_Registry::get('logger');
Log an exception:
$exception = new Zend_Exception('Test exception');
$logger->err($exception);
Log a message:
$logger->info('Show Information about something');
//initiate the logger - Log to a file
$writer = new Zend_Log_Writer_Stream($root.'\log\test.txt');
$logger = new Zend_Log($writer);

$columnMap = array('lvl' => 'priority', 'msg' => 'message', 'timestamp' => 'timestamp', 'lvlName' => 'priorityName');
$dbwriter = new Zend_Log_Writer_Db($db, 'log_table_name', $columnMap);
$logger->addWriter($dbwriter);
//Log to firebug
$writerFirebug = new Zend_Log_Writer_Firebug();
$writerFirebug->setPriorityStyle(6, 'TRACE');
$logger->addWriter($writerFirebug);
$registry->logger = $logger;
Using the logger:
$logger = Zend_Registry::get('logger');
Log an exception:
$exception = new Zend_Exception('Test exception');
$logger->err($exception);
Log a message:
$logger->info('Show Information about something');

Code Sniffer
Asbtract:
PHP_CodeSniffer is a PHP5 script that tokenises and "sniffs" PHP and JavaScript code to detect violations of a defined coding standard. It is an essential development tool that ensures your code remains clean and consistent. It can also help prevent some common semantic errors made by developers.
Download:
http://pear.php.net/package/PHP_CodeSniffer/download
Install:
pear install PHP_CodeSniffer
Using:
phpcs /path/to/code/my_dir
PHP_CodeSniffer is a PHP5 script that tokenises and "sniffs" PHP and JavaScript code to detect violations of a defined coding standard. It is an essential development tool that ensures your code remains clean and consistent. It can also help prevent some common semantic errors made by developers.
Download:
http://pear.php.net/package/PHP_CodeSniffer/download
Install:
pear install PHP_CodeSniffer
Using:
phpcs /path/to/code/my_dir
Using TextMate with PHP_CodeSniffer.
Quick Start
1. Install PHP command line.
2. Install PHP_CodeSniffer PEAR package.
3. Download PHP_CodeSniffer command v0.1 from here.
4. Unzip the downloaded file.
5. Install the bundle by double clicking the icon.
Once the bundle is installed, you have to update two lines of code to make it work in your system.
One is the path to php executable file on the first line of the code. The typical location on OS X is /usr/bin/php.
Next, you need to change the path to PHP_CodeSniffer installation. In most of systems, ‘/usr/bin/phpcs’ would work just fine.
Now you are ready to go. Try to open your PHP code in TextMate, then the default setup will let you run the command by pressing ‘Shift + Apple Key + C’. It will display the output window like:
Introduction
I have been a PHP developer more than 2 years now and have been using JEdit as primary text editor until recently I switched to TextMate. Despite of excellent editing power and numerous great plugins, the slow nature of Java really put me down and has been consistently irritating. After several trials on various alternative text editors on mac, I ended up using TextMate that satisfies me good enough to give up good old JEdit.
During my daily coding duties, I use PHP_CodeSniffer (a.k.a phpcs) to validate my PHPcode against my company’s coding standards, typically on the command line using Terminal. Only the problem is that I have to type the path to the file name whenever I need update different files. It is not really efficient especially you are working on big project with many many files. Thankfully ‘Commands’ in TextMate gave me a nice nifty shortcut to run phpcs on without jumping to Terminal app.
One of the biggest advantage of using TextMate is Commands. It is a powerful tool that TextMate can have certain level of integration with external scripts. What phpcs_cmd does is simply to run PHP_CodeSniffer on your opened PHP source code, then displays the result in HTML format. The command itself is also written in PHP.
Using PHP_CodeSniffer
PHP_CodeSniffer is PEAR package that tokenises and “sniffs” PHP code to detect violations of a defined set of coding standards. It is an essential development tool that ensures that your code remains clean and consistent. It can even help prevent some common semantic errors made by developers. It is now used by PEAR community. Every PEAR code is checked by PHP_CodeSniffer everyday and reports the errors to developers.
You can find the documentation for more details on PEAR website or Greg Sherwood’s blog who is the maintainer of this package.
PHP với Simple XML lib
PHP - XML
1. The ExtensibleMarkup Language (XML): là ngôn ngữ đánh dấu với mục tiêu là đơn giản hóa
việc chia sẻ dữ liệu giữa các hệ thống khác nhau
Cú pháp XML cơ bản cho một phần tử là
<tên thuộc_tính="giá trị">nội dung</tên>
Cấu trúc XML đơn giản:
<?xml version="1.0"?>
<message>Hello, World!</message>
Ví dụ: Hãy tạo tệp tin XML có nội dung như sau:
Đây là tệp tin XML:
<?xml version="1.0" encoding="utf-8"?>

2. SimpleXML
• Parsing XML Documents
// Load an XML string
$xmlstr = file_get_contents(’library.xml’);
$library = simplexml_load_string($xmlstr);
hoặc dùng
// Load an XML file
$library = simplexml_load_file(’library.xml’);
• Truy cập Children and Attributes
<?php
// Load an XML string
$library = new SimpleXMLElement("library.xml", NULL, true);
foreach ($library->book as $book)
{
echo $book["isbn"] . "<br>";
echo $book->title . "<br>";
echo $book->author . "<br>";echo $book->publisher . "<br><br>";
}
?>
• Để hiển thị các thuộc tính và giá trị: dùng hàm SimpleXMLElement::children() và
SimpleXMLElement::attributes(), SimpleXMLElement::getName()
foreach ($library->children() as $child)
{
echo $child->getName() . ":\n";
// Get attributes of this element
foreach ($child->attributes() as $attr)
{
echo " " . $attr->getName() . ": " . $attr . "<br>";
}
// Get children
foreach ($child->children() as $subchild)
{
echo " " . $subchild->getName() . ": " . $subchild . "<br>";
}
echo "<br>";
3. XPath Queries: được dùng để lấy ra values của các Elements hay Attributes XPath đóng một
vai trò quan trọng trong việc trao đổi dữ liệu giữa các computers hay giữa các chương trình ứng
dụng vì nó cho phép ta lựa chọn hay sàng lọc ra những tin tức nào mình muốn để trao đổi hay
hiển thị.
$library = new SimpleXMLElement("library.xml", NULL, true);
$results = $library->xpath("/library/book/title");
foreach ($results as $title)
{
echo $title . "<br>";
}
// Search the first child element
$results = $library->book[0]->xpath("title");foreach ($results as $title)
{
echo $title . "<br>";
}
• Thay đổi tài liệu XML
$library = new SimpleXMLElement("library.xml", NULL, true);
$book = $library->addChild("book");
$book->addAttribute("isbn", "0812550706");
$book->addChild("title", "Ender's Game");
$book->addChild("author", "Orson Scott Card");
$book->addChild("publisher", "Tor Science Fiction");
header("Content-type: text/xml");
echo $library->asXML();
• Xóa một phần tử:
$library->book[0] = NULL;
• Làm việc với Namespaces:
<?xml version="1.0"?>
<library xmlns="http://example.org/library"
xmlns:meta="http://example.org/book-meta"
xmlns:pub="http://example.org/publisher"
xmlns:foo="http://example.org/foo">
<book meta:isbn="0345342968">
<title>Fahrenheit 451</title>
<author>Ray Bradbury</author>
<pub:publisher>Del Rey</pub:publisher>
</book>
</library>$namespaces = $library->getDocNamespaces();
foreach ($namespaces as $key => $value)
{
echo "{$key} => {$value}<br>";

For filtering add following to the bootstrap file:
$filter = new Zend_Log_Filter_Priority(Zend_Log::INFO);
$logger->addFilter($filter);
This will make sure no debug messages are logged.
