VersiÃ³n	DescripciÃ³n
4.3.0	Se convierte en un alias de apache_request_headers(). BÃ¡sicamente, fue renombrada. Esto se debe a que esta funciÃ³n solo trabaja con Apache.

Notes

Nota: A partir de PHP 4.3.3 se puede usar tambien esta funcion con el modulo de servidor NSAPI de los servidores web, Netscape/iPlanet/SunONE.

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;

}

?>

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.
