Rather than concatenating strings, you can use commas with echo as well:
echo "<td>", ($i * 8) + $j, "</td>";
I *think* that you may in fact get a VERY SLIGHT increase in performance by
doing it this way, because PHP will simply dump each 'piece' to the output
buffer/to the browser one by one rather than having to go through the work
of building one large string and then outputting that.
Caveats: This won't work if you use the function-like syntax for echo <<
echo(foo, bar, baz) /* this won't work */ >>, but as your example code
doesn't use it I'm imagining you probably aren't either.
