**phpQuery** depends on following code parts:
  * [PHP5](#PHP5.md)
  * [PHP5 DOM extension](#DOM_extension.md)
  * [Zend Framework](#Zend_Framework.md)

## PHP5
Required version of PHP is [PHP5](http://www.php.net/), **5.2** recommended.

## DOM extension
PHP5's build-in [DOM extension](http://php.net/manual/en/book.dom.php) is required. Users of
[windows XAMPP](http://www.apachefriends.org/en/xampp-windows.html) (and maybe other unofficial PHP distributions) need to disable depracated [DOM XML](http://php.net/manual/en/ref.domxml.php) extension. More information can be found in [this post on mrclay.org](http://mrclay.org/index.php/2008/10/08/getting-phpquery-running-under-xampp-for-windows/)

## Zend Framework
[Zend Framework](http://framework.zend.com/) is used as HTTP Client and JSON encoder. Those who already have Zend Framework in their applications, can remove directory **/phpQuery/Zend**. Only condition is having proper include path set for own copy of the library.
