We recently needed to convert a complex array structure to an object-based one in PHP. We started off with Marcel’s array2object function but realized that we only wanted to “objectify” associative arrays, and leave non-associative arrays to as arrays. So here’s the final function, using vhermecz’s function to detect associative arrays:

function array2object($data) {
   if (!is_array($data)) return $data;
   $is_assoc = is_assoc($data);

   $object = new stdClass();

   if (count($data) == 0) return $data;

   if (is_array($data) && count($data) > 0) {
      foreach ($data as $name=>$value) {
         if ($name !== '') {
            $object->$name = array2object($value);
            $data[$name] = array2object($value);
         }
      }

   }
   if ($is_assoc)
        return $object;
   else
        return $data;
}


function is_assoc($var) {
    return is_array($var) && array_keys($var)!==range(0,sizeof($var)-1);
}
