Edit report at http://bugs.php.net/bug.php?id=52684&edit=1 ID: 52684 Updated by: salathe@php.net Reported by: chinawolfs at hotmail dot com Summary: document problem with class_exists function -Status: Open +Status: Feedback Type: Documentation Problem Package: Documentation problem Operating System: window xp PHP Version: 5.2.14 Block user comment: N New Comment: Your sample code will raise a warning on line 4 (Missing argument 1 for php::home()) and a notice on line 5 (Undefined variable: url); it will create a new instance of the php class. If a value is passed along to the method call, your script works fine. Could you elaborate on the nature of the documentation bug, please? I don't see it.

Test script: --------------- <?php class php { private $_url = null; public function home($url) { $this->_url = $url; return $this->_url; } } if(class_exists('php')) { $php = new php(); } print_r($php->home()); ?> Expected result: ---------------- $php is a new object and print_r home() method ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52684&edit=1
