phpQuery depends on following code parts:

• PHP5
• PHP5 DOM extension
• Zend Framework

PHP5

Required version of PHP is PHP5, 5.2 recommended.

DOM extension

PHP5's build-in DOM extension is required. Users of windows XAMPP (and maybe other unofficial PHP distributions) need to disable depracated DOM XML extension. More information can be found in this post on mrclay.org

Zend Framework

Zend Framework 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.
