Как вы предоставляете параметры int [] в Flex PHP Service

Question

Мой Flex Service Call возвращается Null, может кто-нибудь сказать мне, где я иду не так?

База данных:

user_id: 1 
user_name: stephen
user_password: qwerty
status: Active

user_id: 2 
user_name: john
user_password: qwerty
status: Passive

user_id: 3 
user_name: marice
user_password: qwerty
status: Awaiting

user_id: 4
user_name: maria
user_password: qwerty
status: Passive

Метод обслуживания PHP:

public function getAllUserByStatus($arrStatus) {

    $rows = array();

    foreach ($arrStatus as $item)
    {
        $stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename WHERE status=?");     
        $this->throwExceptionOnError();

        mysqli_stmt_bind_param($stmt, 's', $item);      
        $this->throwExceptionOnError();

        mysqli_stmt_execute($stmt);
        $this->throwExceptionOnError();

        mysqli_stmt_bind_result($stmt, $row->user_id, $row->user_name, $row->user_password, $row->status);

        while (mysqli_stmt_fetch($stmt)) {
          $rows[] = $row;
          $row = new stdClass();
          mysqli_stmt_bind_result($stmt, $row->user_id, $row->user_name, $row->user_password, $row->status);
        }

        mysqli_stmt_free_result($stmt);
    }

    mysqli_close($this->connection);
    return $rows;
}

Тестовый запрос PHP:

<code><?php 
    include('UserService.php'); 
    $o = new UserService(); 
?>

<pre>
<?php 
    var_dump($o->getAllUserByStatus(array('Active','Passive')));
?>

Результат теста PHP:

array
  0 => 
    object(stdClass)[4]
      public 'user_id' => int 1
      public 'user_name' => string 'stephen' (length=7)
      public 'user_password' => string 'qwerty' (length=6)
      public 'status' => string 'Active' (length=6)
  1 => 
    object(stdClass)[5]
      public 'user_id' => int 2
      public 'user_name' => string 'john' (length=4)
      public 'user_password' => string 'qwerty' (length=6)
      public 'status' => string 'Passive' (length=7)
  2 => 
    object(stdClass)[3]
      public 'user_id' => int 4
      public 'user_name' => string 'maria' (length=5)
      public 'user_password' => string 'qwerty' (length=6)
      public 'status' => string 'Passive' (length=7)

Приложение Flex (возвращает ноль, почему):

Answer 1

Если event.result не является ArrayCollection, то попытка привести его к одному просто приведет к нулевому назначению.Попробуйте сделать acUser экземпляром Array и приведите к нему ваш event.result.
