# get_headers

(PHP 5)

get_headers -- Fetches all the headers sent by the server in response to a HTTP request

## Description

array get_headers ( string url [, int format] )

get_headers() returns an array with the headers sent by the server in response to a HTTP request. Returns `FALSE` on failure and an error of level `E_WARNING` will be issued.

If the optional format parameter is set to 1, get_headers() parses the response and sets the array's keys.

> Notatka: Since PHP 5.1.3 this function uses the default stream context, which can be set/changed with the stream_context_get_default() function.

Przykład 1. get_headers() example

`<?php $url = 'http://www.example.com'; print_r(get_headers($url)); print_r(get_headers($url, 1)); ?>`
