Checkboxes, $_POST array, and switch statement

I'm having problems with a switch statement that is wrapped in a
foreach statement so that each index in an array is evaluated against
the switch statement. The switch/case will then return some output for

I have a long list of classes for the upcoming semester. Each one has a
checkbox to the right that has the following code. <input
type="checkbox" name="course[]" value="i"> where i increases linearly
with each class, i.e. first class value="1" second value="2". There are
41 classes for the semester. Upon submission of the form (Yes, I have a
<form> tag with all the necessary parameters.), display.php (the action
of the form) should loop through each key in the course array and
evaluate the value against a switch statement. Here is what my PHP code
looks like so far:

if(isset($_POST['course']) {
   foreach ($_POST['course'] as $key => $value) {
         case 1:
                   echo 'foo';
         case 2:
                  echo 'bar';
                  echo 'Please select a course';

I tried putting the case numbers in quotes like

case "1":

but that didn't make any different. What this will eventually do is
pull book information for each class that is selected from Amazon and
enable the user to quickly add the books to a shopping cart and check
out. I shortened the code (leaving out the other 39 cases!) and I
omitted the html that the PHP page contains. Can anyone explain what I
am doing wrong with my switch statement and/or array?

Needs braces after switch to enclose the cases:
        switch($value) {
           case 1:

ljb, thanks for your kind response. As John Reuben would say, "Thanks
to everyone who chose to bite their tongue instead of busting us out;
you could have made us look dumb. But you didn't, and I appreciate the
courtesy..." I keep telling people I know just enough PHP to be
dangerous and annoying.
