I believe you are incorrect. Switch will look for the first case statement that is true and execute that statement. The following works - case one is incorrect so it doesn't get executed but the second case does. Paste this into a test.php file and you will see it works.. Read the manual. $a=2; $b=4; switch (true) { case ($a < $b) and ($b > 5): echo "Incorrect"; case ($a == 2): echo "Correct"; } So my original question is still stands. The switch statement is correct, but there is a problem with my conditional statements. ----- Original Message ----- From: "Rick Emery" <remery@emeryloftus.com> To: "Beauford.2002" <beauford.2002@rogers.com>; "PHP General" <php-general@lists.php.net> Sent: Thursday, December 19, 2002 7:33 PM Subject: Re: [PHP] Another problem with conditional statements > switch() does not work that way.
