You probably want something like
print while (<$fh>);
You could also store the file to an array first, or "slurp" the file,
if you want to eliminate the loop.

Once more, just so we're clear on this: This isn't C, you don't need
to worry about code optimization.
Relax; don't worry; have a homebrew.

how reactive you have the luxury to be will depend mostly on your

Thanks for the reply. There is a lot I don't know to chew on.
Could you just clue me in on a few things:

If your goal here is just to allow scrolling and you're not doing
anything else with the form, though, it may be ti

really be taint checking anyway, so modifying the regex shouldn't be
too hard. In your action form, just do the opposite, more or less, of

Try something more like

Whichever it is, giving some specific code you're having troubl

The best way to benchmark queries is from the command line, or
phpmyAdmin, which is designed for this. You can also use MySQL

If you need to make sure the user sees the info as it was at the time
