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".

I've got some code from someone else I've inherited and need to sort out
some problems with. The programmer that wrote it originally was much
better than I and programmed a little over my head to say the least.
One function that I've come across that has 5 variables as input:
function($var1,$var2,!$var2,$var3->cc,$var3->bcc);
The question I have is on the 3rd input variable, what does the "!" in
front of $var2 do to that variable?

Hmmm. Looks like a weird mistake, to be sure. If $var2 is boolean it should
pass the opposite of its current state. Is $var2 a boolean? It is being
passed twice here, once AS and once AS NOT.
