stdClass to array?

Question

i have:

stdClass Object
(
    [0] => stdClass Object
        (
            [one] => aaa
            [two] => sss
        )

    [1] => stdClass Object
        (
            [one] => ddd
            [two] => fff
        )

    [2] => stdClass Object
        (
            [one] => ggg
            [two] => hhh
        )
}

and i must get this with keys, for example:

$var = $stdClass[0];

but i have error:

Fatal error: Cannot use object of type stdClass as array in

Is possible parse this stdClass to array and use this with keys?

Why is it a `stdClass` to begin with, can't you create it as array? — deceze, Jul 09 '12 at 13:30
Sure just do: **$arrayRepresentation = (array) $someStdClass;** — Bartosz Grzybowski, Jul 09 '12 at 13:32

Cast it to an array:

$array = (array)$stdClass;

`$array = json_decode($jsonData, true);` does not work? Please show a full example, including what the JSON data looks like. – deceze Jul 09 '12 at 13:48
if i use true then i have empty array. If i use yout solution this working only for current array - children array still are stdClass – Lucci Fangorci Jul 09 '12 at 13:52
Yes, the children will still be `stdClass` objects, you'll have to cast them as well. – deceze Jul 09 '12 at 13:56

If you're using json_decode to convert that JSON string into an object, you can use the second parameter json_decode($string, true) and that will convert the object to an associative array.

If not, what everybody else has said and just type cast it

$array = (array) $stdClass;

You should have no problem using `json_decode` is you do: `$array = json_decode($string, true);` Then using `print_r` will give the associative array with the keys. – Marcus Recck Jul 09 '12 at 13:46

Your problem is probably solved since asking, but for reference, quick uncle-google answer:

function objectToArray($d) {
  if(is_object($d)) {
    $d = get_object_vars($d);
  }
  if(is_array($d)) {
    return array_map(__FUNCTION__, $d); // recursive
  } else {
    return $d;
  }
}

this working only for current array. Childrens array still are stdObject – Lucci Fangorci Jul 09 '12 at 13:52
@LucciFangorci You didn't mentioned, that you want the whole tree. For now I don't even see a reason, why: `echo $array[0]->two`. – KingCrunch Jul 09 '12 at 13:59

Of course you can typecast, $var = (array) $obj;, but I would suggest ArrayAccess to your class.

By using ArrayAccess, you can then treat your objects and data as if it was an array, or natively as an object.

Cast it into an array. Currently it is not readable to PHP as an array.

$array = (array)$stdClass;

Essentially, just type cast it:

$arr = (array)$obj;
$var = $arr[0];

But read the caveats here.

since you've got objects inside of objects, you'll need to cast the containing object to an array and iterate it. While iterating through it, access the property you want `$var->one`. – dnagirl Jul 09 '12 at 13:58

If you have an nested array you can used json_encode and json_decode to convert the whole object to an array:

$result = json_decode(json_encode($source), JSON_OBJECT_AS_ARRAY);

This one worked for me, The decoding and encoding makes for a regular array

$array = json_decode(json_encode($object), True);

function load_something () : \stdClass {

    $result = new \stdClass();

    $result->varA   = 'this is the value of varA';
    $result->varB   = 'this is the value of varB';
