Demo:1 homepage directly) results: $_server["query_string"] = "$_server[" Request_uri "] ="/"$_server[" script_name "] ="/ index.php "$_server[" php_self "] ="/index.php "

Http:// (with Query) results: $_server["query_string"] = "p=1" $_server["request_uri"] = "/?p=1" $_server["Script_ NAME "] ="/index.php "$_server[" php_self "] ="/index.php "

The differences between the four variables are mastered by Query_string,request_uri,script_name and php_self in the $_server function by example.
