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);
Did you know?Explore Trending and Topic pages for more stories like this.

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?
