note 77633 added to function.uniqid

This function is painfully slow if you're using it to give images random names inside of a loop. The following function will give you a random name *every* time and is much faster. <?php function nameImage($imgExtension) { return time() . substr(md5(microtime()), 0, rand(5, 12)) . $imgExtension; } ?> ---- Server IP: 209.41.74.194 Probable Submitter: 65.185.136.246 ---- Manual Page -- http://www.php.net/manual/en/function.uniqid.php Edit -- https://master.php.net/note/edit/77633 Del: integrated -- https://master.php.net/note/delete/77633/integrated Del: useless -- https://master.php.net/note/delete/77633/useless Del: bad code -- https://master.php.net/note/delete/77633/bad+code Del: spam -- https://master.php.net/note/delete/77633/spam Del: non-english -- https://master.php.net/note/delete/77633/non-english Del: in docs -- https://master.php.net/note/delete/77633/in+docs Del: other reasons-- https://master.php.net/note/delete/77633 Reject -- https://master.php.net/note/reject/77633 Search -- https://master.php.net/manage/user-notes.php
