Easiest way to implode() a two-dimensional array?

Question

I\'m new to PHP, and don\'t have quite the grip on how it works. If I have a two dimensional array as such (returned by a database):

array(3) {   
    [0]=&

Check out the below from the PHP implode() manual:

 $val ) {
        if ( is_array( $val ) )
            $val = implode( ',', $val );
        $string[] = "{$key}{$glue}{$val}";

    }
    return implode( $separator, $string );

}
?>

If you only want to return the value (and not the key), just modify the above to use $string[] = "{$val}";.
