**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.
