As far as I can tell, apache_request_headers() provides the same information as $_SERVER , but with slightly different keys. Why would anyone use apache_request_headers() rather than just getting this information from $_SERVER ? I am working with PHP 5.3.18 with Apache on Centos. thank you
EDIT. identical data from $_SERVER and apache_request_headers()
