My apologies, I knew in my wall of text I would omit things. That code in its entirety is actually –

  $value = '21';

  // format value
  if( !$value || $value == 'null' )
  {
    return false;
  }

  // temp convert to array
  $is_array = true;

  if( !is_array($value) )
  {
    $is_array = false;
    $value = array( $value );
  }

  foreach( $value as $k => $v )
  {
    $user_data = get_userdata( $v );

    //cope with deleted users by @adampope
    if( !is_object($user_data) )
    {
      unset( $value[$k] );
      continue;
    }

    $value[ $k ] = array();
    $value[ $k ]['ID'] = $v;
    $value[ $k ]['user_firstname'] = $user_data->user_firstname;
    $value[ $k ]['user_lastname'] = $user_data->user_lastname;
    $value[ $k ]['nickname'] = $user_data->nickname;
    $value[ $k ]['user_nicename'] = $user_data->user_nicename;
    $value[ $k ]['display_name'] = $user_data->display_name;
    $value[ $k ]['user_email'] = $user_data->user_email;
    $value[ $k ]['user_url'] = $user_data->user_url;
    $value[ $k ]['user_registered'] = $user_data->user_registered;
    $value[ $k ]['user_description'] = $user_data->user_description;
    $value[ $k ]['user_avatar'] = get_avatar( $v );

  }

  // de-convert from array
  if( !$is_array && isset($value[0]) )
  {
    $value = $value[0];
  }

Sorry about that.

So this was my code, but my issue from before still stands. I wouldn’t be able to output the array of $value and check the types using gettype as I previously mentioned if this was not the case.

I updated my original post to reflect this, so it’s not confusing to someone reading it for the first time. Thanks!
