Php中的循环验证

Question

我想在php中验证许多字段，所以我可以在php中使用循环来验证这些字段吗?我现在使用以下代码

    if(empty($add_data['first_name']))
        {
            $responseJSON = array("Status" => false,"Message" => "please enter first_name");
            header("content-type:application/json");
            $response = json_encode($responseJSON);
            echo $response; 
        }
    elseif(empty($add_data['last_name'])))
        {
            $responseJSON = array("Status" => false,"Message" => "please enter your last_name");
            header("content-type:application/json");
            $response = json_encode($responseJSON);
            echo $response; 
        }
    ...and so on...

如何在循环中验证？提前感谢

创建字段数组及其错误消息，例如

$fields = array('first_name' => "please enter first_name",
                'last_name'  => "please enter your last_name");

然后，您可以遍历此数组以检查所有值并发出相应的错误消息：

foreach ($fields as $field => $error) {
    if(empty($add_data[$field])) {
        $responseJSON = array("Status" => false,"Message" => $error);
        header("content-type:application/json");
        $response = json_encode($responseJSON);
        echo $response; 
    }
}
