PHP, Echoing an array into a string of comma seperated values

This seems like it should be fairly straight-forward for experienced PHP coders… which I’m not.

This is what I have so far:

<?php echo $cfs->get_labels('name'); ?>: <?php $values = $cfs->get('name');
    foreach($values as $value => $label) {echo $value . ', ';}
?>

How could I avoid having a comma printed on the last value in something like this?

I’ve referred to this and similar, but can’t seem to crack it.

Answer 1

You can use echo implode(',', $values); instead of the foreach loop.

EDIT: whoops, I just noticed you output the keys, so for that you can use:

echo implode(',', array_keys($values));
