How to JSON encode a user array using PHP?

Question

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);
  }

not sure what you are asking here, your loop is pointless, the variables inside `$result` get replaced on each loop iteration so the content of `$result` will always be the value of the last `$user` in the loop. — Julien, Apr 23 '19 at 02:25
thats not 100% correct. For each user there is in users, return the following 3 results from that user and encode it as a json. im sure its possible to do. — Mic, Apr 23 '19 at 02:28
You need to put the results in an array, not just overwrite the same elements each time. — Barmar, Apr 23 '19 at 02:34

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);
