5.4.0 | This function became available under FastCGI. Previously, it was supported only when PHP was installed as an Apache module.
4.3.3 | As of PHP 4.3.3 you can use this function with the NSAPI server module in Netscape/iPlanet/SunONE webservers, too.
4.3.0 | Became an alias for apache_request_headers(). Essentially, it was renamed. This is because this function only works with Apache.
