Hello,
Coming from a *cough*Pascal background, with sprinkles of C, and Java, I was wondering if there was a different way to exchange one variable to another without having to use variables that are temporary, such as an example like this (which could eventually be used to sort information, or some such:)

$temporary = $first;

$first = $second;

$second = $temporary;

Is there a way that I can make $first exchanged with $third, without having to use the extra (wasteful) variable $next?

I have heard from a friend that there is a way to do this, but didn't tell me.
