PHP Json decode not work in laravel - php

Question

I have a C# client, its send a json to my php server.
There is the json string:
{"data":[{"name":"1"}]}
Its a valid json. When i try it in PHP Sandbox its works good
$ad = '{"data":[{"name":"1"}]}';
$contents = utf8_encode($ad );
$results = json_decode($contents);
var_dump($results->data);
But,when i try in laravel 5.1, its not work good.
$response = $connection -> getData();
// return $response; (Its equal : {"data":[{"name":"1"}]} )
$contents = utf8_encode($response);
$results = json_decode($contents);
dd($results->data); // Error Trying to get property of non-object
I hope someone can help me.
Thanks!

Based on the comments, it looks like the socket_read() in the getData() method is reading 1 character at a time, and then concatenating each NUL terminated character into a response string. json_decoded() is choking on all the extra NUL characters.
You can either update your logic in the getData() method so it is not doing this, or you can run a str_replace on the results:
$response = $connection -> getData();
// get rid of the extra NULs
$response = str_replace(chr(0), '', $response);
$contents = utf8_encode($response);
$results = json_decode($contents);
dd($results->data);
