http_response_code — Get or Set the HTTP response code

说明

int http_response_code ([ int $response_code ] )

If you pass no parameters then http_response_code will get the current status code. If you pass a parameter it will set the response code.

参数

response_code

The optional response_code will set the response code.

<?php
http_response_code(404);
?>

返回值

The current response code. By default the return value is int(200).

范例

Example #1 Examples using headers_list()

<?php

// Get the current default response code
var_dump(http_response_code()); // int(200)

// Set our response code
http_response_code(404);

// Get our new response code
var_dump(http_response_code()); // int(404)
?>
