note 39155 added to control-structures.switch

Did you know that switch() and case() can also accomodate things like basic math calculations and counter incrementing? They do. In this example, I use a switch statement (which is inside of a while loop) to alternate the background color of a table row. It gives me a cool spool-printer-paper effect. $rows_per_color = 5; // change bgcolor every 5 rows switch($ctr++) { case 0: $bgcolor = "#ffffff"; break; case ($rows_per_color): $bgcolor = "#ff0000"; break; case ($rows_per_color * 2): $bgcolor = "#ffffff"; $ctr = 1; break; } As you can see, I increment $ctr by 1 in the switch() itself, and the final case() does a simple calculation. Simple, but powerful. [Remember, the above example is inside of a while() loop... each time it iterates, switch increments $ctr.] ---- Manual Page -- http://www.php.net/manual/en/control-structures.switch.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+39155 Delete -- http://master.php.net/manage/user-notes.php?action=delete+39155&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+39155&report=yes Search -- http://master.php.net/manage/user-notes.php
