How to Efficiently Convert a PHP stdClass Object to an Array?

Converting an stdClass to Array in PHP

Question:

I need to convert a PHP stdClass object into an array. However, attempts using (array) casting, json_decode(true), and json_decode() have resulted in an empty array. How can I perform this conversion effectively?

Answer:

Lazy One-Liner Method

For a slightly compromised performance, you can leverage the JSON methods to achieve this conversion in a concise manner:

$array = json_decode(json_encode($booking), true);

This method first encodes the object into a JSON string and then decodes it back into an array.

Converting stdClass to Array

$array = (array) json_decode(json_encode($booking));

This approach returns an indexed array without preserving property names.

Converting stdClass to Associative Array

$array = json_decode(json_encode($booking), true);

By passing true as the second argument to json_decode, you can convert the object into an associative array, preserving property names.

Custom Function (Recursive)

If performance is critical, you can implement a custom recursive function to convert the object to an array:

function object_to_array($object) {
  if (is_object($object)) {
    $object = get_object_vars($object);
  }

  if (is_array($object)) {
    return array_map(__FUNCTION__, $object);
  } else {
    return $object;
  }
}

$array = object_to_array($booking);
