Re: method overloading in a class

Would something like this work for you? class foo { public function bar($arg1, $arg2, $arg3=null) { if (isset($arg3)){ { return $this->_bar3($arg1, $arg2, $arg3); } else { return $this->_bar2($arg1, $arg2); } } also you may want to look into the func_get_args function.
