Is there a single line of code to do the following?
I'm trying to interchange two variables' contents... I can do it with the
following, but I was just wondering... I can't find it if there is...
$a = "abc";
$b = "def";
$temp = $b;
$b = $a;
$a = $temp;
//now $a = "def" and $b = "abc"
Thanks in advance,
John
