Human Readable Random String


 / Published in: PHP
 

This code will create a human readable string that will look more close to dictionary words, useful for captchas.

  1. /**************
  2. *@length - length of random string (must be a multiple of 2)
  3. **************/
  4. function readable_random_string($length = 6){
  5. $conso=array("b","c","d","f","g","h","j","k","l",
  6. "m","n","p","r","s","t","v","w","x","y","z");
  7. $vocal=array("a","e","i","o","u");
  8. $password="";
  9. srand ((double)microtime()*1000000);
  10. $max = $length/2;
  11. for($i=1; $i<=$max; $i++)
  12. {
  13. $password.=$conso[rand(0,19)];
  14. $password.=$vocal[rand(0,4)];
  15. }
  16. return $password;
  17. }
