                )
        )

i used array_walk and array_push, array_merge function...

i got this error for all above functions

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

if javascript wanted, please add an example in literal notation. — Nina Scholz, Jul 02 '18 at 10:05
Best is to json_encode the object and decode back to array. Check this link https://stackoverflow.com/questions/19495068/convert-stdclass-object-to-array-in-php — Penguine, Jul 02 '18 at 10:11

You need to understand that stdClass Object uses class variable names. So it will not be possible to use number 1 as a variable name. Instead, go for something like:

...
[2] => stdClass Object
 (
  [qty] => 2
  [id] => 2
  [name] => Single 1 Tag Innenraum 2
  [one] => Array(
        [name] => jiya
        [sirname] => rathod
      )
  [two] => Array(
        [name] => jiya
        [sirname] => rathod
      )
...

Replace the number with a valid variable name, e.g one as above.

To add new element, you can call:

wk[1][2]->one = Array(
        [name] => jiya
        [sirname] => rathod
      );

Which is easily accessible via wk[1][2]->one

You could solve this in two ways:

1) Convert object to array

2) Assign new array to the object, naming it "persons" or the like:

$wk[1][2]->persons = array(); // Or via foreach, etc.

and then use array_push to insert into that array:

array_push($wk[1][2]->persons, '...');

[wk] => Array
    (
        [1] => Array
            (
                [2] => stdClass Object
                    (
                        [qty] => 2
                        [id] => 2
                        [name] => Single 1 Tag Innenraum 2
                        [persons] => Array(
                            [1] => Array(
                                [name] => jiya
                                [sirname] => rathod
                                    ),
                            [2] => Array(
                                [name] => pinal
                                [sirname] => rathod
                                    ),
                         )

                    )

                [3] => stdClass Object
                    (
                        [qty] => 1
                        [id] => 3
                        [name] => test1
                    )

            )
    )
