  "sender": "btknctTR",
  "title": "(Sistem) btknctTR - Son mesajları.",
  "date": "May 8, 2016 4:46:13 PM",

    {
      "sender": "btknctTR",
      "message": "asd",
      "date": "May 8, 2016 11:47:45 PM"
    },
    {
      "sender": "btknctTR",
      "message": "/asd",
      "date": "May 8, 2016 11:47:46 PM"
    },
    {
      "sender": "btknctTR",
      "message": "/report btknctTR",
      "date": "May 8, 2016 11:47:51 PM"
    },
    {
      "sender": "Speaw",
      "message": "tamam",
      "date": "May 8, 2016 11:56:39 PM"
    },
    {
      "sender": "KaptanUcar",
      "message": "peki",
      "date": "May 10, 2016 6:19:26 PM"
    }
  ]
}

I want to add a new message to "messages" array and convert string to json. This is a support system. How can I do it?

It's pretty simple, just convert (decode) the JSON into a PHP array, add the new message data, and re-encode it to a JSON string!

Sample Code:

$array = json_decode($inputJSON);
$array['messages'][] = ['sender'=>'sample', 'message'=>'sample', 'date'=>'sample'];
$jsonOutput = json_decode($array);
