note 17675 deleted from function.usort by jimw

I am using PHP 4.0.4 and could not get example #3 for usort to work, nor could I understand the syntax, i.e. uasort($a, array ("TestObj", "cmp_obj")); At http://www.zend.com/zend/list_change_4.php, I found a relevant change in PHP 4: "Allow all functions that receive user-defined function callbacks to accept an array that contains an object and a method name, in place of a function name, e.g. usort($array, array($obj, "ObjSort")) (Zeev, Zend Engine)" So, the function must be passed an array containing and object and a method NAME - therefore, this corrects the example: uasort($a, array ($a[0], "cmp_obj")); Note that the class does not work: uasort($a, array ($TestObj, "cmp_obj")); It seems to want an instance of the class.
