http_response_code

(PHP 5 >= 5.4.0, PHP 7, PHP 8)

http_response_code — Get or Set the HTTP response code

Beschreibung

http_response_code(int $response_code = 0): int|bool

Gets or sets the HTTP response status code.

Parameter-Liste

response_code

The optional response_code will set the response code.

Rückgabewerte

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).

Beispiele

Beispiel #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());
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

int(200)
int(404)

Beispiel #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());
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

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