note 101075 added to function.mt-rand

If you want to generate an EXTREMELY FAST random serial using '0123456789abcdefghijklmnopqrstuvwxyz' you can use: <?php base_convert(mt_rand(0, 0x38E38E38E38E38E), 10, 36); ?> You may need to change the 0x38E38E38E38E38E to whatever your (PHP_INT_MAX / 36) is. that number is for 64 bit machines, 32 bit machines will be: 0x38E38E3. on on 64 bit machines it gives roughly between a 1 to 12 character number. on a 32 bit machine it will return roughly 1 to 5 characters. If you do some simple math you can get it to always return a certain number of characters. ---- Server IP: 69.147.83.197 Probable Submitter: 12.71.233.34 ---- Manual Page -- http://www.php.net/manual/en/function.mt-rand.php Edit -- https://master.php.net/note/edit/101075 Del: integrated -- https://master.php.net/note/delete/101075/integrated Del: useless -- https://master.php.net/note/delete/101075/useless Del: bad code -- https://master.php.net/note/delete/101075/bad+code Del: spam -- https://master.php.net/note/delete/101075/spam Del: non-english -- https://master.php.net/note/delete/101075/non-english Del: in docs -- https://master.php.net/note/delete/101075/in+docs Del: other reasons-- https://master.php.net/note/delete/101075 Reject -- https://master.php.net/note/reject/101075 Search -- https://master.php.net/manage/user-notes.php
