[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! */ }
