Recursive chmod in PHP

@author Jeppe Toustrup (tenzer at tenzer dot dk)
@param $path An either relative or absolute path to a file or directory
which should be processed.
@param $filePerm The permissions any found files should get.
@param $dirPerm The permissions any found folder should get.
@return Returns TRUE if the path if found and FALSE if not.
@warning The permission levels has to be entered in octal format, which
normally means adding a zero ("0") in front of the permission level.

Function invocation and ‘this’ Context Example
//Define our objects
var o1 = {handle:'o1'};
var o2 = {handle:'o2'};
var o3 = {handle:'o3'};
//Set handle to window
window.handle = 'window';
function whoAmI() {

}
//Create method in object 01
o1.identifyMe = whoAmI;
alert(whoAmI()); //Alerts 'window'
alert(o1.identifyMe()); //Alerts 'o1'
alert(whoAmI.call(o2)); //Alerts 'o2' (call is running whoAmI in the context of o2)
alert(whoAmI.apply(o3)); //Alerts 'o3' (apply is running whoAmI in the context of o3)
