How to store an array as a comma seperate list in a variable?

Experts,

I have an array of information that is passed by my form.  I have been able to process the form data passed using a foreach loop such as:

foreach($_POST[departments] as $departments) {
echo $department;
echo '<br />';
}

The code above prints something like this:

department1
department2
department3
etc.

How can I store the values passed by my form in a variable?  The variable should store the information in the following format:

department1, department2, department3, etc.

if you need comma + Space then the first argument to implode() shoud be a COMMA + space instead of just comma:
$myList = implode(", ", $_POST['departments']);
echo $myList;
