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.
