You can customize what string is generated and how long
- function random($length)
- {
- $hash = '';
- $chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz';
- $max = strlen($ chars) - 1 ;
- mt_srand((double)microtime() * 1000000);
- for($i = 0; $i < $length; $i++)
- {
- $hash .= $chars[mt_rand(0, $max)] ;
- }
- return $hash;
- }
