php - from mongodb to array with objects -

-

it must better way this? want documents sounds collection , output them array objects in (using backbone.js). it cant object objects in! 

$sounds = iterator_to_array($db->sounds->find());      $a = "[";      foreach ($sounds $id => $sound) {         $a .= json_encode($sound) . ",";     }      //remove last comma...     $a = substr($a, 0, -1);     $a .="]";      echo $a;

you try:

$sounds = iterator_to_array($db->sounds->find()); echo json_encode(array_values($sounds));

array_values return values of associated array indexed array json_encode return json encoded string in format want (i.e. javascript array instead of javascript object).

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
