$fish = 1;
$$add++;
echo "fish is now: $fish<br />\n";

You may also want to consider using:

<input type="submit" name="add[fish]" value="Fish" />

You can then look into the $_POST['add'] array and find 'fish' as the
key with http://php.net/key or similar functions.

Variable variables might be a bit tricky to understand and easy to
mess up, but arrays are, for MOST users, easier.
