To do exactly what you're trying to do, do something like:

for my $i (0 .. $MAX_ROWS - 1) {
    push @fee, ${"foo_$i"};
}

That said, DON'T DO IT THAT WAY.

That is what's called a "soft reference". Since you're coming from the web, you should know it's a security leak. Taint-checking fails that. strict fails that. (You are using string and -T, right?)

As for a better solution, you need to change your form. CGI should be able to handle arrays. (You are using CGI, right?)

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
