PHP Library provides a standard library interface which allows developers to take full advantage of Object Oriented Programming in PHP. This library of interfaces creates a standard API for certain kinds of built-in functionality, allowing your classes to interact with the PHP engine in a much more seamless manner. The functionality it provides includes, (for example) is the ability to define how your objects will react when iterated over for each, advanced array access, file and directory access, and advanced SimpleXML object handling.

Therefor to simplify your development process I have collected Useful PHP Libraries and Classes, that would help you with your development related tasks, and help you to achieve desired results within given deadline. Enjoy !!
