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. -- Daniel Grace <[EMAIL PROTECTED]> -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
