How to compile a PHP extension

Posted by Kelvin on 29 Jun 2010 | Tagged as: PHP, programming

Short answer

sudo apt-get install php5-dev

cd /path/to/extension

The extension directory must have a minimum of

1. config.m4
2. php_sample.h
3. sample.c

phpize

./configure
make
sudo make install

Now add the dynamic extension to your php.ini files in /etc/php5.

;;;;;;;;;;;;;;;;;;;;;;
;
; If you wish to have an extension loaded automatically, use the following
; syntax:
;
;   extension=modulename.extension
;
; For example, on Windows:
;
;   extension=msql.dll
;
; … or under UNIX:
;
;   extension=msql.so
;
; Note that it should be the name of the module only; no directory information
; needs to go here.  Specify the location of the extension with the
; extension_dir directive above.
; Example lines:
extension=sample.so

Using expressions to assign PHP static variables

Posted by Kelvin on 14 Jan 2010 | Tagged as: PHP, programming

OK. The PHP manual explicitly states you CANNOT use an expression when assigning to a static variable.

You can, however, do this:

class MyClass {
  public static $a = 1;
  public static $b;

  public static function init() {
    self::$b = self::$a + 1;
  }
}
MyClass::init();

Nifty eh?

LightVC – a simple and elegant PHP framework

Posted by Kelvin on 28 Sep 2009 | Tagged as: PHP, programming

Whilst working on a recent project involving clinical trials, I stumbled on LightVC, a php framework. Yes.. yet ANOTHER php framework.

Its emphasis on simplicity and minimalism caught my eye and I decided to give it a whirl.

3 months later, I have to admin I'm a total fan. It makes the simple stuff easy, and the tough stuff.. well.. possible. It is a pure view-controller framework w/o ORM. Perfect because my backend is usually handled by Solr anyway.

Highly recommended if you're not already invested in Zend or one of the biggies (cakephp, symfony, etc)
