[Resolved] why does'nt this array print using pc_array_to_comma_string

[sgtpepper]

This is my first attempt at arrays and using the function pc_array_to_comma_string.

Here is my code:

<?
$array = array('Scott', 'clif', 'leslie', 'mary', 'ashley', 'poop');

function pc_array_to_comma_string($array) {

    switch (count($array)) {
    case 0:
            return'';

    case 1:
            return reset($array);

    case 2:
            return join(' and ' , $array);

    default:
            $last = array_pop($array);
            return join(', ', $array) . ", and $last";
}
}
?>

What am I doing wrong? I am getting no results....I was anticipating a string seperated by ,

This works fine here ... how are you calling the function...?

[sgtpepper]

<?
print 'Here is my test ' . join(', ', $array) . '.';
?>

This displays

Here is my test Scott, clif, leslie, mary, ashley, poop.

I thought is would be

Here is my test Scott, clif, leslie, mary, ashley, and poop.

<?
$array = array('Scott', 'clif', 'leslie', 'mary', 'ashley', 'poop');

function pc_array_to_comma_string($array) {

    switch (count($array)) {
    case 0:
            return'';

    case 1:
            return reset($array);

    case 2:
            return join(' and ' , $array);

    default:
            $last = array_pop($array);
            return join(', ', $array) . ", and $last";
}
}

$this=pc_array_to_comma_string($array);
echo $this;

?>
