# getallheaders

(PHP 4, PHP 5)

getallheaders — Fetch all HTTP request headers

### Description

array getallheaders ( void )

Fetches all HTTP headers from the current request.

This function is an alias for apache_request_headers(). Please read the apache_request_headers() documentation for more information on how this function works.

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

### Return Values

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

### Changelog

Version | Description
--- | ---
4.3.0 | Became an alias for apache_request_headers(). Essentially, it was renamed. This is because this function only works with Apache.

### Examples

Example #1 getallheaders() example

`<?php
foreach (getallheaders() as $name => $value) {
echo "$name: $value\n";
}
?>`

### Notes

> Note: As of PHP 4.3.3 you can use this function with the NSAPI server module in Netscape/iPlanet/SunONE webservers, too.
