[PHP] Easy question...grabbing variables...

[Jeff Lewis]

Um, been using PHP for awhile now and don' even know how to grab these:

http://wwbl.hyrum.net/send_email.php?to=4;from=25

I have usually only passed one variable before so all I've need to do is $toID=$to but 
how do I get from?  I know I should know this but I am either having a major brain 
fart or missed this in PHP 101 ;)
