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]=&

You asked for a two-dimensional array, here's a function that will work for multidimensional array.

function implode_r($g, $p) {
    return is_array($p) ?
           implode($g, array_map(__FUNCTION__, array_fill(0, count($p), $g), $p)) : 
           $p;
}

I can flatten an array structure like so:

$multidimensional_array = array(
    'This',
    array(
        'is',
        array(
            'a',
            'test'
        ),
        array(
            'for',
            'multidimensional',
            array(
                'array'
            )
        )
    )
);

echo implode_r(',', $multidimensional_array);

The results is:

This,is,a,test,for,multidimensional,array
