I found an easy way to call a parent method in PHP < 5.3 without entering the method name directly: <?php class MyClass extends AnotherClass { function _myOverrideMethod() { call_user_func(array('parent',__FUNCTION__)); } } ?> This will call the parent method of the current class (AnotherClass::_myOverrideMethod). I also tried replacing __FUNCTION__ with __METHOD__ but that DOES NOT WORK. I var_dump'ed __METHOD__ and realied it included the class name. So, for example, calling var_dump(__METHOD__) within the class above will output 'MyClass::_myOverrideMethod' which will not work when used as a replacement for __FUNCTION__ above because the call_user_func then tries to call 'parent::MyClass::_myOverrideMethod' which DOES NOT WORK. __FUNCTION__ included only the method name (without the class). To compare: here are the outputs side-by-side: <?php // Supposing they were called within the MyClass::_myOverrideMethod method above... var_dump(__METHOD__); // MyClass::_myOverrideMethod var_dump(__FUNCTION__); // _myOverrideMethod ?> ---- Server IP: 69.147.83.197 Probable Submitter: 150.134.171.76 ---- Manual Page -- http://www.php.net/manual/en/function.call-user-func-array.php Edit -- https://master.php.net/note/edit/98221 Del: integrated -- https://master.php.net/note/delete/98221/integrated Del: useless -- https://master.php.net/note/delete/98221/useless Del: bad code -- https://master.php.net/note/delete/98221/bad+code Del: spam -- https://master.php.net/note/delete/98221/spam Del: non-english -- https://master.php.net/note/delete/98221/non-english Del: in docs -- https://master.php.net/note/delete/98221/in+docs Del: other reasons-- https://master.php.net/note/delete/98221 Reject -- https://master.php.net/note/reject/98221 Search -- https://master.php.net/manage/user-notes.php
