Comma on array, except last value via PHP [duplicate]

Question

Possible Duplicate:
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.

I'm pretty sure this has been asked before. Try using the search feature next time. — Fad

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));
