[PHP] help needed with crypt()

[chandrakantreddy]

Hi

    The script is not working.

   function authenticate($user,$pass) {
         $result = -1;
         $data = file("shadow"); /* permission every
one read */

         foreach($date as $line ) {
            $arr = explode(":",$line); 
             if($arr[0] == $user) {
              /* user name matching */
             if(crypt(trim($pass),$salt) == $arr[1])
               {  $result = 1;
                    break;
                }
              else
               {
                   $result = 0;
                    break;
                }
           }  /* end of for */
          return $result ;

}


The above programme always returs -1.

Any help would be appreciated.
