Digg  getallheaders
Fetch all HTTP request headers
(PHP 4, PHP 5)
Code Examples / Notes » getallheadersjukkaho
This function really is useful. Although $_SERVER['HTTP_*']-variables seem to include all request headers, they are really only the most generally needed - not all of them. One example that needs this functionality is Digest Authentication (http://www.ietf.org/rfc/rfc2617.txt). When implementing it in PHP script, you can't read client's "Authorization"-header without this function. tigr
Just a bit faster version of ZevS' function (does not use regular expressions and does not require POSIX regexps that is in PECL in php6): <?php function emu_getallheaders() { foreach($_SERVER as $name => $value) if(substr($name, 0, 5) == 'HTTP_') $headers[substr($name, 5)] = $value; return $headers; } ?> zevs
if PHP installed not as Apache-module: <?php function emu_getallheaders() { foreach($_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" lorro
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.

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; } ?> jarl
