   Bug description:  $this->AuthTblCols[$colname] == 0 => false

   Short:
   In a class "if ($this->arr[$keyname] != 0);" will allways be false.

   Long:
   <?
   class Auth {
     var $AuthTblCols = array('login'      => 'login',
                              'passwd'     => 'passwd',
                              'access_lvl' => 0,
                              'last_login' => 0);

   //.... snip ....
      function ColOK($colname, $str) {
       print_r("<pre>ColOK:");
   var_dump($this->AuthTblCols[$colname]);print_r("</pre>");
   /* returns string 'access_lvl' (see under) */
         if (!empty($this->AuthTblCols[$colname]) &&

             !($this->AuthTblCols[$colname] == 0)
   /* The Line above will allways evaluate false!!?!
   at first I had:
   $this->AuthTblCols[$colname] != 0
   But it also evaluates false.*/
         ) {
   print_r("HERE");
            return (empty($str)?true:$str);
         }
         return false;
      }
       function somefunc() {
   // a func inside the class will call ColOK()
         if (!$str = $this->ColOK('access_lvl',
                                  "somestring I want returned")) echo "Not
   ok";
   //.... snip ....
   }

   $auth = new Auth();
   $auth->AuthTblCols = array('login'      => 'login',
                              'passwd'     => 'passwd',
                              'access_lvl' => 'access_lvl',
                              'last_login' => 'last_login');
   if (!$auth->A_func_that_will_run_somefunc()) {
     echo "Invalid login/password";
     exit;
   }
   ?>

Any ideas?
