# apache_request_headers

(PHP 4 >= 4.3.0, PHP 5)

apache_request_headers -- Fetch all HTTP request headers

## Beskrivelse

array apache_request_headers ( void )

Fetches all HTTP requests from the current request.

This function is only supported when PHP is installed as an Apache module.

## Returneringsværdier

An associative array of all the HTTP headers in the current request, or `FALSE` on failure.

## Eksempler

Eksempel 1. apache_request_headers() example

`<?php $headers = apache_request_headers(); foreach ($headers as $header => $value) { echo "$header: $value <br />\n"; } ?>`

Ovenstående eksempel vil udskrive noget der ligner:

    Accept: */*
    Accept-Language: en-us
    Accept-Encoding: gzip, deflate
    User-Agent: Mozilla/4.0
    Host: www.example.com
    Connection: Keep-Alive

## Notes

> Bemærk: Prior to PHP 4.3.0, apache_request_headers() was called getallheaders(). After PHP 4.3.0, getallheaders() is an alias for apache_request_headers().

> Bemærk: You can also get at the value of the common CGI variables by reading them from the environment, which works whether or not you are using PHP as an Apache module. Use phpinfo() to see a list of all of the available environment variables.

> Bemærk: Fra PHP 4.3.3 kan du også bruge denne funktion med NSAPI server modulet i Netscape/iPlanet/SunONE webservere.
