note 114785 added to function.class-exists

Beware: class_exists is case-INsensitive, as is class instantiation. php > var_dump(class_exists("DomNode")); bool(true) php > var_dump(class_exists("DOMNode")); bool(true) php > var_dump(class_exists("DOMNodE")); bool(true) php > $x = new DOMNOdE(); php > var_dump(get_class($x)); string(7) "DOMNode" (tested with PHP 5.5.10 on Linux) This can cause some headaches in correlating class names to file names, especially on a case-sensitive file system. ---- Server IP: 212.124.37.9 Probable Submitter: 195.14.234.228 ---- Manual Page -- http://php.net/manual/en/function.class-exists.php Edit -- https://master.php.net/note/edit/114785 Del: integrated -- https://master.php.net/note/delete/114785/integrated Del: useless -- https://master.php.net/note/delete/114785/useless Del: bad code -- https://master.php.net/note/delete/114785/bad+code Del: spam -- https://master.php.net/note/delete/114785/spam Del: non-english -- https://master.php.net/note/delete/114785/non-english Del: in docs -- https://master.php.net/note/delete/114785/in+docs Del: other reasons-- https://master.php.net/note/delete/114785 Reject -- https://master.php.net/note/reject/114785 Search -- https://master.php.net/manage/user-notes.php
