PHP: I get a completely blank page, I don't know how to debug this in PHP

Question

I\'m having some issues to debug this in php. When I include this line:

require_once(\"http://\" . $_SERVER[\"HTTP_HOST\"] . \"/dompdf/dompdf_config.inc.php\");
         


        

Answer 1

This a very unusual and insecure way to include files, but yet if you still want to use it, make sure that the file you're including isn't being executed on the remote server since you probably targeting the php source code on the require_once here not the final output of it.
