如何在数组中存储表单验证错误

Question

如果我有一些基本的表单验证，（只是为了简单而使用empty（））并希望将这些错误消息放入数组中，我将如何实现？

 $errors = array();
 $response = array();

if(empty($_POST['name'])) {

    $errors['name'] = "Name required";
}

if(empty($_POST['email'])) {

    $errors['email'] = "Email required";
}

$response['errors'] = $errors;

if(!empty($errors)) {

    $response['success'] = false;
    $response['message'] = "fail";

} else {

    $response['success'] = true;
    $response['message'] = "<div class='alert alert-success'>Success</div>";
}

echo json_encode($response);
}

    $message = [];

if(empty($_POST['name'])) {

array_push($message , "Name required <br />");

}

if(empty($_POST['email'])) {

array_push($message , "Email required <br />");

}

if(!empty($message)) {
foreach ( $message as $str)
echo "<div class='alert alert-danger'>" . $str . "</div>";

} else {
// success 

}
