Ooops.. I made the same mistake in my private reply.. hah..

= = = Original message = = =

I took me a little while to notice that it wasn't a function declaration :p

~It's just as Jay said, it's calling "function" with those arguments, 
where '!$var2' extends to '!(bool)$var2' or "treat/cast this value as/to 
boolean, and pass it's inverted value" or "NOT $var2".
