note 73696 added to function.array-key-exists

Further research on this has turned up that the performance problems are a known, confirmed bug in PHP 5.1.x, and have been fixed in PHP builds after September 2006. You can find the bug report here: http://bugs.php.net/bug.php?id=38812 However, just because it's a fixed bug doesn't really change the conclusion. If you're writing a script and there's any chance it could be used on a PHP 5.1.x server, you should still avoid this function and use isset() or some other kind of test if you want it to run efficiently. ---- Server IP: 216.194.113.175 Probable Submitter: 71.225.5.53 ---- Manual Page -- http://www.php.net/manual/en/function.array-key-exists.php Edit -- https://master.php.net/note/edit/73696 Del: integrated -- https://master.php.net/note/delete/73696/integrated Del: useless -- https://master.php.net/note/delete/73696/useless Del: bad code -- https://master.php.net/note/delete/73696/bad+code Del: spam -- https://master.php.net/note/delete/73696/spam Del: non-english -- https://master.php.net/note/delete/73696/non-english Del: in docs -- https://master.php.net/note/delete/73696/in+docs Del: other reasons-- https://master.php.net/note/delete/73696 Reject -- https://master.php.net/note/reject/73696 Search -- https://master.php.net/manage/user-notes.php
