stdClass to array?

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?

function load_something () : \stdClass {

    $result = new \stdClass();

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

    return $result;
}

$result = load_something();

echo ($result instanceof stdClass)?'Object is stdClass':'Object is not stdClass';
echo PHP_EOL;

print_r($result);

//directly extract a variable from stdClass 
echo PHP_EOL . 'varA = ' . ($result->varA);

//convert to array, then extract
$array = (array)$result;
echo PHP_EOL . 'varA = ' . $array['varA'];

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);

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;
  }
}

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.

stdClass is an object so u can access value from it like

echo stdClass->one;

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;
