How to “flatten” a multi-dimensional array to simple one in PHP?

Question

It\'s probably beginner question but I\'m going through documentation for longer time already and I can\'t find any solution. I thought I could use implode for each dimensio

Answer 1

any of this didnt work for me ... so had to run it myself. works just fine:

function arrayFlat($arr){
$out = '';
    foreach($arr as $key => $value){

        if(!is_array($value)){
            $out .= $value.',';
        }else{
            $out .= $key.',';
            $out .= arrayFlat($value);
        }

    }
    return trim($out,',');
}


$result = explode(',',arrayFlat($yourArray));
echo '
';
print_r($result);
echo '
';
