problem with the randomic generation of salt when a use $string = crypt("11lei11lao11") it allways generates a salt ( the first 2 chars from encrypted string ) that if use crypt("11lei11lao11blablabla") would work, and also crypt("11lei11lao11anythingwouldworkhere").

the code is

$cryptedpass = crypt("11lei11lao11");
if (crypt ( "11lei11lao11anythingwouldworkhere", substr ( $cryptedpass, 0, 2)) == $cryptedpass) {    
  echo "this is extremely strange for me";
}

and this works with this pass but not whit others!!!!!!!!!!!!!!!!!
