    if (isset($_config[$key])) {
    return $_config[$key];
    } else {
    return $config_not_defind;
    }
    }
    }
    使用例子:
    从应用端发过来的参数为
    $arr = array('letter_number'=>'abc123', 'account'=>'acb1234_');
    //参数验证
    $_msg = Validation::validate($arr, 'test');
    if ($_msg !== null) {
    return $_msg . ' is invalid parameter';
    }
随便看
