[Ed: You're now using the (indeed yet undocumented) ${expression} syntax]
Creating variable variables on the fly..
I had a problem I needed to get "n" variables named
"x_1, x_2 .... x_n".
To do this when n is passed as a parameter I used a little (undocumented?) trick.
for($i=0;$i<$n;$i++){
$finalvar=${"x_$i"}; /* this is the trick! */
}
