php setting status code

http_response_code() function is used to get/set the HTTP status code of the response

Syntax:

http_response_code ($response_code)

Parameters:

• response_code: The optional response_code will set the status code of the response.

Return value:

• If response_code is provided, the previous status code will be returned. If response_code is not provided, the current status code will be returned. In a web server environment, the default value for these status codes is 200.

• If called in a non-Web server environment (such as a CLI application), if response_code is not provided, false will be returned. In a non-web server environment, providing response_code will return true (only if the status code has not been previously set).

Example:

<?php
// 获取当前状态码，并设置新的状态码
var_dump(http_response_code(404));
//获取新的状态码
var_dump(http_response_code());
?>

The above routine will output:

int(200)
int(404)
