There are plenty of situations where it's useful. For example, if you're displaying data in rows and want to shade every other row: if ( 1 == $row_count % 2 ) { echo "<tr><td>$data</td></tr>"; } else { echo "<tr><td class='shade-1'>$data</td></tr>"; } Or if you have a data set you want to display in an HTML table across multiple rows, you'll probably find it useful for determining when to put <tr> or </tr> as you loop through your data set and use it to calculate whether you will need to fill cells at the end of the table with non-breaking spaces. There are many other applications, but these two come up pretty frequently in web applications. -- Steve Werby COO 24-7 Computer Services, LLC Tel: 804.817.2470 http://www.247computing.com/
