Arrays and outputting commas and &s

[nimzie]

I have a list that I am iterating through presently as:

<code>
<?php
foreach ( $node->field_artist as $item) {
print $item['view']. ' ';
}
?>
</code>

It outputs a straight up list. Say the items in the list are
Adam
John
Ben
Steve

I would like to output
Adam, John, Ben and Steve

or if it's just Adam , output:
Adam

or Adam and John, output:
Adam and John

or if it's
Adam
John
Ben, output:
Adam, John and Ben

Thanks for any help!

I suggest something along these lines:

if (!empty($node->field_artist)) {
    $temp = $node->field_artist;
    $last = array_pop($temp);
    if (!empty($temp)) {
        echo implode(', ', $temp) . ' and ';
    }
    echo $last;
}
