Thanks

You do realise it's:

 

echo $_SERVER['HTTP_REFERER'];

 

And not:

 

echo $_SERVER['HTTP_REFERRER'];

 

There is no double R.

 

This is taken directly from the PHP Manual, something you should've looked at:

The address of the page (if any) which referred the user agent to the current page. This is set by the user agent. Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted.

 

I highlighted the important parts.

Thanks for your reply But it didn't work either:

echo $_SERVER['HTTP_REFERER'];

$_SERVER['HTTP_REFERER'] is an optional header that the browser provides when it makes a http request. If it is not set, then it is not set and you cannot do anything about it.
