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

Sure just do: $arrayRepresentation = (array) $someStdClass; — Bartosz Grzybowski

Cast it to an array:

$array = (array)$stdClass;

Where does that data come from to begin with?

Lucci Fangorci Over a year ago

i use json and json_decode function. I add for this function parameter true, but still i have empty array

deceze Over a year ago

$array = json_decode($jsonData, true); does not work? Please show a full example, including what the JSON data looks like.

Lucci Fangorci Over a year ago

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

deceze Over a year ago

Yes, the children will still be stdClass objects, you'll have to cast them as well.

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.

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;
  }
}

if now user $array[0] then i have empty array

Lucci Fangorci Over a year ago

this working only for current array. Childrens array still are stdObject

KingCrunch Over a year ago

@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.

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;

$array[0][one] will return aaa

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.

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';
    $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'];
