comma separated list in php

Question

I am trying to build a list separated by commas which should look like this (green, orange, red).

$i=0;
$taxonomy = $form_state[values][taxonomy][5];
foreach ($t         


        

Answer 1

Someone posted it and I was going to upvote, but they removed it. I think mysql GROUP_CONCAT would be a good solution, since it looks like getting a comma separated list is the only purpose of this query.
