note 42221 added to function.uniqid

This function returns unique 12 characters long 36 base string (chars 0-9A-Z) - this is often nicer than the 32 characters that md5 gives. /* 36 ^ 12 = 4738381338321616896 which is 19 chars long hence adding of random 0 - 3 if $str is shorter than 19 chars */ function uniq_12_str() { $str = uniqid('',FALSE); $str = base_convert($str, 16, 10) $str = strrev($str); while(strlen($str) < 19) { $str = rand(0,3) . $str; } $str = base_convert($str, 10, 36); $str = str_pad($str, 12 ,'0' ,STR_PAD_LEFT) $str = strtoupper($str); return $str; } ---- Manual Page -- http://www.php.net/manual/en/function.uniqid.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+42221 Delete -- http://master.php.net/manage/user-notes.php?action=delete+42221&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+42221&report=yes Search -- http://master.php.net/manage/user-notes.php
