Echo a multidimensional array in PHP

I have a multidimensional array and I'm trying to find out how to simply "echo" the elements of the array. The depth of the array is not known, so it could be deeply nested.

In the case of the array below, the right order to echo would be:

This is a parent comment
This is a child comment
This is the 2nd child comment
This is another parent comment

This is the array I was talking about:

Array
(
    [0] => Array
        (
            [comment_id] => 1
            [comment_content] => This is a parent comment
            [child] => Array
                (
                    [0] => Array
                        (
                            [comment_id] => 3
                            [comment_content] => This is a child comment
                            [child] => Array
                                (
                                    [0] => Array
                                        (
                                            [comment_id] => 4
                                            [comment_content] => This is the 2nd child comment
                                            [child] => Array
                                                (
                                                )
                                        )
                                )
                        )
                )
        )

    [1] => Array
        (
            [comment_id] => 2
            [comment_content] => This is another parent comment
            [child] => Array
                (
                )
        )
)

if you wanted to store it as a variable you could do:

recurse_array($values){
    $content = '';
    if( is_array($values) ){
        foreach($values as $key => $value){
            if( is_array($value) ){
                $content.="$key<br />".recurse_array($value);
            }else{
                $content.="$key = $value<br />";
            }

        }
    }
    return $content;
}

$array_text = recurse_array($array);

Obviously you can format as needed!
