  <p>Can anyone please help me! The error i've been getting is <strong><em>Error Parsing Data Org.json.JSONException: Value cannot be converted to JSONObject</em></strong></p>
  
  <p>Heres the JSON string</p>
  
  <pre><code>Array{"Users":[{"UserID":"1","FirstName":"lalawee","Email":"12345","Password":null},{"UserID":"2","FirstName":"shadowblade721","Email":"12345","Password":null},{"UserID":"3","FirstName":"dingdang","Email":"12345","Password":null},{"UserID":"4","FirstName":"solidsnake0328","Email":"12345","Password":null}],"success":1}
  </code></pre>
  
  <p>Is the error lying in the JSON parser class?</p>
  
  <p>EDIT: here the code for the php script that outputs the array above. can anyone tell me what's wrong with the php script that outputs the word array before the json string? Sorry for the trouble. I'm new to coding. Been following online tutorials but stuck on this for a few days now.</p>
  
  <pre><code>&lt;?php
  /*
  * Following code will list all the Users
  */
  // array for JSON response
  $response = array();
  // include db connect class
  require_once __DIR__ . '/db_connect.php';
  // connecting to db
  $db = new DB_CONNECT();
  // get all Users from Users table
  $result = mysql_query("SELECT * FROM Users") or die(mysql_error());
  // check for empty result
  if (mysql_num_rows($result) &gt; 0) {
  // looping through all results
  // Users node
  $response["Users"] = array();
  
  while ($row = mysql_fetch_array($result)) {
      // temp user array
      $user[] = array();
      $user["UserID"] = $row["UserID"];
      $user["FirstName"] = $row["FirstName"];
      $user["Email"] = $row["Email"];
      $user["Password"] = $row["Password"];
  
      // push single User into final response array
      array_push($response["Users"], $user);
  }
  // success
  $response["success"] = 1;
  echo $response;
  
  // echoing JSON response
  echo json_encode($response);
  }
  else {
  // no Users found
  $response["success"] = 0;
  $response["message"] = "No Users found";
  
  // echo no users JSON
  echo json_encode($response);
  }
  ?&gt;
