http_response_code
(PHP 5 >= 5.4.0, PHP 7)
http_response_code — Get or Set the HTTP response code
Description
mixed http_response_code ([ int $response_code ] )
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)
