[PHP] Array to List

[James Johnson]

Hello,

Coming from ColdFusion, this is difficult. CF has an ArrayToList() function.
I can't find anything similar in PHP.

I'm building a list from an array with the following code, but it puts a
trailing "," and I need to remove it.

                $campusList = "";
                foreach ($_POST['campus'] as $campus_ID){
                        $campusList .= $campus_ID;
                        $campusList .= ",";
                        }
                print($campusList);

I've tried this:
                if($campusList <> ""){
                        $chr = ",";
                        $campusList = strrchr($campusList,$chr);
                }

But it removes everything from the list, except 1 ","

Thanks,
James
