php - Better way of error handling? -

what best way of error handling? came with:

class test {      public static function payment($orderid, $total) {         if (empty($orderid) && empty($total)) {             return array('status' => 'fail', 'error' => 'missing data');         }     }  } 

i heard try/exceptions how fit code? if provide example great!

as mentioned, use exceptions. specific example, throw exception if condition fails. when envoke method can throw exception, wrap try/catch handling block.

class test {   public static function payment( $orderid, $total ) {     if (empty( $orderid ) && empty( $total )) {         throw new exception('missing data');     }   } }   try {   test::payment("1", "2"); //should fine   test::payment(); //should throw exception } catch (exception $e){   echo $e;   //do other things if need  }
