如何使用return

Question

我不知道如何在变量和数组中传递，如何在foreach循环中传递$ query变量并使用return

public function test($id){
    $sql = 'SELECT * FROM '.SELF::TABLE_MEMBERS_CONTAINER. ' c
        LEFT JOIN '.SELF::TABLE_MEMBER.' m ON
        c.members_id = m.id
        LEFT JOIN '.SELF::TABLE_CONTAINER.' ct ON
        c.container_id = ct.id
        WHERE c.members_id =  '. $id . '  ORDER BY c.created_at  desc';
        $row = $this->query_rows( $sql );
    foreach ($row as $r ) {
        $i++;
        $sql = 'SELECT * FROM `'.SELF::TABLE_STATUS_CONTAINER.'` WHERE container_id = ' .$r['container_id'];
        $query = $this->query_rows( $sql );
        var_dump($query);
    }
    return array(
     'data'=>$row,
    );
}

我试着

return array(
 'data'=>$row,
 'query'=>$query,
);

当我在内部循环var_dump时它返回

bool(false)
array(2) {
  [0]=>
  array(7) {
    ["id"]=>
    string(1) "1"
    ["container_id"]=>
    string(1) "3"
    ["title"]=>
    string(51) "teat"
  }
  [1]=>
  array(7) {
    ["id"]=>
    string(1) "2"
    ["container_id"]=>
    string(1) "3"
    ["title"]=>
    string(72) "te"at
  }
}
bool(false)

但是当我转移到外部循环时，它只返回
