very easy function to generate keys without substr: <?php function randomkeys($length) { $pattern = "1234567890abcdefghijklmnopqrstuvwxyz"; for($i=0;$i<$length;$i++) { $key .= $pattern{rand(0,35)}; } return $key; } echo randomkeys(8),"<br>"; echo randomkeys(16),"<br>"; echo randomkeys(32),"<br>"; echo randomkeys(64),"<br>"; ?> output: n94bv1h7 y9qi1qu2us3wged2 00dhax4x68028q96yyoypizjb2frgttp 478d4ab0ikapaiv0hk9838qd076q1yf46nh0ysigds6ob2xtl61odq2nx8dx7t2b ---- Server IP: 66.163.161.117 Probable Submitter: 89.57.254.228 ---- X-Spam-Status: No, hits=3.3 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER, HTML_MESSAGE autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.rand.php Edit -- http://master.php.net/note/edit/63906 Del: integrated -- http://master.php.net/note/delete/63906/integrated Del: useless -- http://master.php.net/note/delete/63906/useless Del: bad code -- http://master.php.net/note/delete/63906/bad+code Del: spam -- http://master.php.net/note/delete/63906/spam Del: non-english -- http://master.php.net/note/delete/63906/non-english Del: in docs -- http://master.php.net/note/delete/63906/in+docs Del: other reasons-- http://master.php.net/note/delete/63906 Reject -- http://master.php.net/note/reject/63906 Search -- http://master.php.net/manage/user-notes.php
