如何在數組中存儲表單驗證錯誤

Question

如果我有一些基本的表單驗證（爲了簡單起見，僅使用empty（））並且想要將這些錯誤消息放入一個數組中，我將如何實現這一點？

$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 

}
