كيفية تغير حالة الرد response status في PHP؟

تستطيع تغير حالة الرد response status من خلال الدالة http_response_code فقط، على النحو التالي:

<?php 

http_response_code(404); // Not Found

يمكنك إستخدام هذه الدالة لمعرفة حالة الطلب الحالية:

<?php

// Get the new response code
var_dump(http_response_code());	// int(404)

في الإصدارات القديمة من PHP كان يتم إستعمال الدالة header:

header("HTTP/1.1 200 OK");
header("HTTP/1.1 404 Not Found");

يُفضل أن تستعمل الدالة http_response_code إن كان إصدار PHP لديك 5.4 أو أعلى.

ملاحظة: طبقًا لمعاير W3 يجب أن تكون رسالة الحالة (مثل OK و Not Found) مطابقة للمعاير، يمكنك الإطلاع عليها من خلال هذه الصفحة، أو من خلال القائمة التالية:
