Note Submitter: my at example dot com ---- One thing that isn't explicitly stated about switch is that, whether blank or not, if you don't include break, it will always proceed to the next case. <?php foreach (array(0, 1, 2, 3, 4) as $foo) { switch($foo) { case 1: echo 'a'; case 0: echo '0'; break; case 2: echo 'b'; case 3: echo 'c'; case 4: echo 'd'; default: echo '<BR>'; } } Will return: abcd 0bcd cd d This can be useful in certain cases, when certain values should be supersets of other values, and can be cleaner than the corresponding if statement. You can use this to call functions and effectively have multiple default cases. <?php switch($install_step) { case MY_CONST_DOWNLOAD: download(); case MY_CONST_INSTALL: install(); case MY_CONST_CLEANUP: cleanup(); case MY_CONST_EMAIL_USER: emailUser(); }
