Description:
Each class or method should include the php documentation at the beginning of the definition.
Solution:
The average phpDoc for a PhP class should contain the following information:
/**
* Short description of the class/method
* Long description of the class/method
* @author First name Last name <name@emailprovider.dom>
* @since Start date
* @see Wiki documentation link
* @package Name of the container module
* @param Type Name Description
* @return Type Name
*/
Of course, for methods inside a class, redundant information should be excluded.
