I am trying to print / echo utm_source, utm_medium and utm_campaign query values using this PHP code;
echo $_GET['utm_source'];
But strangely for some unknown reason on my server its not printing the values, when I replace utm_source to something else like test_source I am able to see the value in print.
Never faced any such issue, can anyone guide me here.
