Gotcha! Thank you for the quick replies

I just started PHP lessons and I have the following: <?php $a=5; $b=8; function add($a,$b) { $total=($a+$b); return $total; } echo "$a + $b = " . add($a,$b) . "<br />"; ?> What happens to the variable $total? If I say echo $total it doesn't print anything. Why can't I say: echo "$a + $b = $total"; ? Thanks in advance!
