Getting stuff out of a function

[Pezmc]

I am not a newbie I have just never figured out how to do this (taught my self php).
I have a function say

function socks(test,sock) {
echo $test
echo "I am a fary:"
echo $sock

$total = $test * $sock;

}

How can I get the total out of the function to use in other places as a variable, is there a returning function or something?

[NogDog]

function socks($test, $sock) {
   $total = $test * $sock;
   return($total);
}
echo socks(2, 3);   // outputs 6

Of course there's a [man]return[/man]ing function! Did you try reading the manual first?
