# http_response_code

(PHP 5 >= 5.4.0, PHP 7)

http_response_code — Get or Set the HTTP response code

### Description

http_response_code ([ int `$response_code` ] ) : mixed

Gets or sets the HTTP response status code.

### Parameters

`response_code`

  The optional `response_code` will set the response code.

### Return Values

If `response_code` is provided, then the previous status code will be returned. If `response_code` is not provided, then the current status code will be returned. Both of these values will default to a `200` status code if used in a web server environment.

`FALSE` will be returned if `response_code` is not provided and it is not invoked in a web server environment (such as from a CLI application). `TRUE` will be returned if `response_code` is provided and it is not invoked in a web server environment (but only when no previous response status has been set).

### Examples

Example #1 Using http_response_code() in a web server environment

`<?php
// Get the current response code and set a new one
var_dump(http_response_code(404));
// Get the new response code
var_dump(http_response_code());
?>`

The above example will output:

    int(200)
    int(404)

Example #2 Using http_response_code() in a CLI environment

`<?php
// Get the current default response code
var_dump(http_response_code());
// Set a response code
var_dump(http_response_code(201));
// Get the new response code
var_dump(http_response_code());
?>`

The above example will output:

    bool(false)
    bool(true)
    int(201)
