PHP http_response_code Get or Set the HTTP response code

http_response_code

(No version information available, might only be in SVN)

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)
 ?>

以上例程会输出：
