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]=&         


        

Answer 1

function recursive_implode($connector=',', $array=[], $implod='keys'){

    if($implod=='keys'){

        $results=implode($connector,array_keys($array));
    }
    else{

        $results=implode($connector,$array);
    }

    foreach($array as $key=> $value){

        if(is_array($value)){

            $results.=$connector.recursive_implode($connector,$value,$implod);
        }
    }

    return $results;
}
