Comma seperated implode & modifying returned string.

Posted on 16th Feb 2014 07:03 pm by admin

I have a PHP post form that posts up to 4 variables. I need whatever variables are passed to be combined into one comma seperated string (eg variable1,variable2,variable3,variable4). This i can do with the code below.

Code: [Select]$combo = array($one, $two, $three, $four);
$list = implode(",", $combo);

my problem is that the form fields are optional by design so that the user doesn't always post all 4 variables. Sometimes they will post 1, sometimes they will post all 4. So if a user only selects two fields and submits the form i will end up with a string looking like:
variable1,variable2,,
when what i really want is (note the removal of the trailing commas at the end of the string):
variable1,variable2

Can anyone point me towards a possible solution for this?
