And even better one, that absolutely mimics getallheaders behaviour (including keynames - first character in each word is uppercase and words separated with '-' instead of underscore), and still does not use regexp:
<?php
function emu_getallheaders() {
foreach($_SERVER as $name => $value)
if(substr($name, 0, 5) == 'HTTP_')
$headers[str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))))] = $value;
return $headers;
}
?>
getallheaders
说明
array getallheaders ( void )Fetches all HTTP requests 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.
此函数仅在 PHP 作为 Apache 模块安装时才可使用。

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

Just a bit faster version of ZevS' function (does not use regular expressions and does not require POSIX regexps that is in PECL in php6):
<?php
function emu_getallheaders() {
foreach($_SERVER as $name => $value)
if(substr($name, 0, 5) == 'HTTP_')
$headers[substr($name, 5)] = $value;
return $headers;
}
?>

Beware that RFC2616 (HTTP/1.1) defines header fields as case-insensitive entities. Therefore, array keys of getallheaders() should be converted first to lower- or uppercase and processed such.

if PHP installed not as Apache-module:
<?php
function emu_getallheaders() {
foreach($_SERVER as $h=>$v)
if(ereg('HTTP_(.+)',$h,$hp))
$headers[$hp[1]]=$v;
return $headers;
}
?>
I put this code to file "/var/www/include", and edit php.ini:
auto_prepend_file = "/var/www/include"

This function really is useful. Although $_SERVER['HTTP_*']-variables seem to include all request headers, they are really only the most generally needed - not all of them.
One example that needs this functionality is Digest Authentication (http://www.ietf.org/rfc/rfc2617.txt). When implementing it in PHP script, you can't read client's "Authorization"-header without this function.

I think the previous poster is new to web development, so to keep the confusion down I recommend that other newbies read a tutorial on the HTTP protocol.
The poster meant well, but server variables have absolutely nothing to do with this function (nor the HTTP protocol). They aren't a part of the received browser header. getallheaders() will return the entire BROWSER header string to an array.
That's all it is supposed to do and as it was pointed out (by smclean) that this is a VERY USEFUL feature for certain applications. That's why I looked up the function in the first place!
So, yes, you must use the $_SERVER array to retrieve server variables. And to understand certain variables passed by the server read up on the CGI protocol.

You can read the HTTP username and password via the Authorization header by decoding its value from base 64 (if you're using the BASIC authorization scheme). For details about using DBM to maintain usernames and passwords, see http://www.web-hosting.com/dbm.html
