Answer 1

Implode should not be inserting a comma at the end of that string there. Are you sure there isn't an empty string at the end of your array sequence?

Either way, to fix the string you have, just get rid of the last character of the string:

$concatUserIds = "44,44,33,44,33,0,";
$concatUserIds = substr($concatUserIds, 0, strlen($concatUserIds) - 1);

Further, if you're not going to be using the non-comma delimited number set, why don't you just add a comma every time you add a user id. That way you don't even have to use the implode function.
