http_referer

[nkeg]

how do you use the http_referer to know the page the user came from? I mean where do you write it, can I just print it to the screen using echo? will it be something like
echo($_SERVER['http_referer']);
but this doesn't work. I know it's wrong but I don't know why. Excuse me if my question is too stupid but I'm really new to php and I'm not yet used to it.

try caps instead in the parameter in server array
