多维数组不返回所有MySQLi行

Question

从下面的图片可以看出，我只在前端找到一排。我应该返回多行。有人知道我做错了吗？

public function chatBoxMembers() {
        $userid = $this->session->userdata('userid');
        $wow = $this->db->get_where('messages', array('messageRecipientId' => $userid));
        foreach($wow->result() as $row) {
            $imUser = array();
            $imUser['friendId'] = $row->messageSentById;
            $imUser['messageBody'] = $row->messageBody;
            $imUser['readStatus'] = $row->readStatus;
            $imUser['activityStatus'] = $row->activityStatus;
            $imUsers[] = $imUser;
        } echo json_encode(array($imUser));
    }

Answer 1

也许你想要： echo json_encode（array（$ imUsers））;

$ imUsers no $ imUser？
