SWITCH statements can be used instead of multiple IF-ELSE statements checking for the same condition.

<?php #switch.php
   $test = 3;

   switch($test)
   {
       case 1:
          echo "this is case 1";
       break;

       case 2:
          echo "this is case 2";
       break;

       case 3:
          echo "this is case 3";
       break;

       default:  //use default for all other cases
           echo "No value specified for test var";
       break;
}

?>
