Correction to what I said before about the fast random number/serial. This will result in an EXTREMELY fast random string using the following characters: "0123456789abcdefghijklmnopqrstuvwxyz" you can use: <?php base_convert(mt_rand(0x1D39D3E06400000, 0x41C21CB8E0FFFFFF), 10, 36); ?> This will be a random number/string always 12 characters. This will only work on 64 bit systems. This will result in a random number/string between: 100000000000 to zzzzzzzzzzzz If you are using a 32 bit system you will need to use: <?php base_convert(mt_rand(0x1679616, 0x39AA3FF, 10, 36); ?> This will result in a 5 character random number/string, between: 10000 to zzzzz ---- 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/102318 Del: integrated -- https://master.php.net/note/delete/102318/integrated Del: useless -- https://master.php.net/note/delete/102318/useless Del: bad code -- https://master.php.net/note/delete/102318/bad+code Del: spam -- https://master.php.net/note/delete/102318/spam Del: non-english -- https://master.php.net/note/delete/102318/non-english Del: in docs -- https://master.php.net/note/delete/102318/in+docs Del: other reasons-- https://master.php.net/note/delete/102318 Reject -- https://master.php.net/note/reject/102318 Search -- https://master.php.net/manage/user-notes.php
