Generate Random String

 / Published in: PHP
 

If you don’t need human readable string, then use this function instead, which will create a random string you can use for user id’s etc.

  1. /*************

  3. */
  4. function generate_rand($l){
  5.   $c= "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
  6.   srand((double)microtime()*1000000);
  7.   for($i=0; $i<$l; $i++) {
  8. 	  $rand.= $c[rand()%strlen($c)];
  9.   }
  10.   return $rand;
