HTTP2 response is returning array as string

[fakharak]

I am getting expected Array as "string" type (under last key ["data"]) in HTTP2 Response object from Swoole's http2 server, why it is a string ? and how to get it back into array().

Details:
The code for server is on this official link:
https://www.swoole.co.uk/docs/modules/swoole-server-taskCo

with added setting 'open_http2_protocol' => true, to make it http2.
And,
Swoole function to send back response object changed to:
$response->end(print_r($result, true));

The client is the last code snippet on official document:
https://www.swoole.co.uk/docs/modules/swoole-coroutine-http2-client

where i am using:
var_dump($cli->read());
instead of $cli->recv();

Here is the complete http2 response (response object) below. i have pointed out the string in response below :

object(Swoole\Http2\Response)#5 (8) {
  ["streamId"]=>
  int(1)
  ["errCode"]=>
  int(0)
  ["statusCode"]=>
  int(200)
  ["pipeline"]=>
  bool(false)
  ["headers"]=>
  array(5) {
    ["server"]=>
    string(18) "swoole-http-server"
    ["date"]=>
    string(29) "Sun, 06 Jun 2021 06:41:35 GMT"
    ["content-type"]=>
    string(9) "text/html"
    ["content-encoding"]=>
    string(4) "gzip"
    ["content-length"]=>
    string(3) "147"
  }
  ["set_cookie_headers"]=>
  array(0) {
  }
  ["cookies"]=>
  array(0) {
  }

/////////////////////////////////////// Here Starts The Issue
  ["data"]=>
  string(299) "Array /////////////////////////// <----This is a string
(
    [1] => Array
        (
            [data] => www.swoole.co.uk
            [code] => 200
            [done] => 1622961694
            [worker_id] => 2
        )

    [0] => Array
        (
            [time] => 0
            [done] => 1622961695
            [worker_id] => 1
        )

)
"
}

Solved:
(_However, it could be more Performing if HTTP Response Object cotained / returned Array data type instead of returning it as a string).

I got the expected array format using code below on "http2 server side" code....

$response->end(json_encode($result));

And, on the "client-side (calling)" code :

print_r(json_decode($cli->read()->data, true));

Note: For ease of understanding, the client-side code above is expandable to:

$json_response_data = $cli->read()->data;
$array_response_format = json_decode($json_data  ,true);
print_r($array_format);
