Is there a way to capture the URL from the page a visitor has come from?

Philip Olson, mark romero,

Yes!  Using the predefined variable HTTP_REFERER, this can be done.  
Read about predefined variables here :
    http://www.php.net/manual/en/language.variables.predefined.php
Not all browsers provide this information but most do.  A couple ways 
to print out this variable is as such :
    print $HTTP_REFERER;
    print getenv('HTTP_REFERER');
Calling this directly will print nothing, a referrer MUST exist.  Also 
it's worth mentioning that referer is a misspelling but that's just how 
it is, here's some information on that :

In a sense, a referer is referred ;-)
