"; # Id = 5 // Obtain the user proxy
Echo $ _ SERVER ['http _ referer']."
"; // Obtain the complete url

Echo 'http: // '. $ _ SERVER ['http _ host']. $ _ SERVER ['php _ SELF']. '? '. $ _ SERVER ['query _ string'];
# Http: // localhost/blog/testurl. php? Id = 5 // Complete url containing the port number
