[FIXED] How to JSON encode a user array using PHP?

Issue

Im working with a JSON file that checks, if a user is typing.

Is there any reason why this would not work?

  // Array of WP_User objects.
  foreach ( $user_query as $user ) {
    $result['whotyping'] = $user_info->whotyping;
    $result['typingto'] = $user_info->typingto;
    $result['typing'] = $user_info->typing;
  }

  echo json_encode($result);

I thought this would work, but it returns nothing by an error.

How do I solve this problem?

  // Array of WP_User objects.
  foreach ( $user_query as $user ) {
    $result['whotyping'] = $user_info->whotyping;
    $result['typingto'] = $user_info->typingto;
    $result['typing'] = $user_info->typing; 
    echo json_encode($result);
  }

Solution

You should make an array of results.

// Array of WP_User objects.
$results = array();
foreach ( $user_query as $user ) {
    $result = array();
    $result['whotyping'] = $user_info->whotyping;
    $result['typingto'] = $user_info->typingto;
    $result['typing'] = $user_info->typing;
    $results[] = $result;
}

echo json_encode($results);
