I have this in my URL;
?utm_source=John%27s%20Source
I want to get the value using this;
echo rawurlencode(stripslashes($_GET['utm_source']));
That does not return anything. However, if I get rid of the _ on 'utmsource' in both the URL and the _GET, it will return this;
John%27s%20Source
Which is exactly what I am looking for. Why can I not do the same with the underscore?
