PHP: Turning multidimensional arrays to single dimension arrays

Question

Basically my app is interacting with a web service that sends back a weird multidimensional array such as:

Array
(
    [0] => Array
        (
                     


        

Answer 1

function flattenArray($input, $maxdepth = NULL, $depth = 0)
{
    if(!is_array($input)){ 
      return $input;
    }

    $depth++;
    $array = array(); 
    foreach($input as $key=>$value){
      if(($depth <= $maxdepth or is_null($maxdepth)) && is_array($value)){
        $array = array_merge($array, flattenArray($value, $maxdepth, $depth));
      } else {
        array_push($array, $value);
        // or $array[$key] = $value;
      }
    }
    return $array;
}
