我有一个网络服务来连接应用程序和网站。它应该只同步已更改的数据。
这是函数的代码：
public function iphoneexportAction()
{
echo "Start of IphoneExport<br/>";
//Basic configuration
$this->_helper->layout()->disableLayout();
$this->_helper->viewRenderer->setNoRender();
$this->_response->setHeader('Content-Type', 'application/json');
$data = $this->_request->getParam('udid');
echo "UDID:".$data;
if (!$data || $data == '')
{//no data received
echo json_encode(array('status' => 7, 'message' => "No UDID value received"));
$logModel = new Application_Model_WsLog();
$logDate = array(
'call_type' => $this->getRequest()->getActionName(),
'output' => json_encode(array('status' => 7, 'message' => "No UDID value received")),
//'input' => print_r($data,true),
'input' => print_r($this->_request,true),);
$logModel->insert($logDate);
return true;
}
//Taking the user info from the database
$userModel = new Application_Model_User();
$user = $userModel->findByEmail($data);
$userLastSync = $user[0]['sync_ts'];
echo "<br/>Date from database:".$userLastSync."<br>";
if (!isset($user[0]))
{//No user exists with that email
echo json_encode(array('status' => 1, 'message' => "user not found."));
$logModel = new Application_Model_WsLog();
$logDate = array(
'call_type' => $this->getRequest()->getActionName(), 'output' => json_encode(array('status' => 1, 'message' => "user not found.")),
//'input' => print_r($data,true),
'input' => print_r($this->_request,true),
);
$logModel->insert($logDate);
return true;
}
if ($user[0]['user_type'] != USERTYPE_BRIDE)
{//User is a bride
echo json_encode(array('status' => 1, 'message' => "User type not bride"));
$logModel = new Application_Model_WsLog();
$logDate = array(
'call_type' => $this->getRequest()->getActionName(), 'output' => json_encode(array('status' => 1, 'message' => "User type not bride")),
//'input' => print_r($data,true),
'input' => print_r($this->_request,true),
);
$logModel->insert($logDate);

//Adds user data to the return values
$return['udid'] = $data;

$settings['budget'] = is_null($bride[0]['bride_weddingBudget']) ? 0 : $bride[0]['bride_weddingBudget'] / 100;
$return['settings'] = $settings;
}
$mappingModel = new Application_Model_Mapping();

echo"<br />";

echo "Task total:".$tasktotal." Tasknum:".$tasknum."<br/>";
if ($tasktotal == $tasknum&&$taskEnded)
{
$sync_ts_time = time();
$sync_ts = date('Y-m-d H:i:s', $sync_ts_time);
$userModel->update(array('sync_ts'=> $sync_ts), array('user_id'=>$user[0]['user_id']));
echo "UPDATED in the database<br/>";
echo $sync_ts;
}
$logModel = new Application_Model_WsLog();
$logDate = array(
'call_type' => $this->getRequest()->getActionName(),
'output' => json_encode($return),
'input' => print_r($data,true),
);
$logModel->insert($logDate);
return true;
}
在函数的末尾有一行是
$userModel->update(array('sync_ts'=> $sync_ts), array('user_id'=>$user[0]['user_id']));
这条线导致它不起作用。因此，如果我评论它，它会遍历每项任务并比较时间，如果数据库中的时间较新，它会将 json 数据创建回应用程序。问题是当我取消注释时，它甚至在开始 foreach 之前就更新了数据库时间戳。
这是评论时的输出
Start of IphoneExport

UPDATE in the database

您可以看到它说 Data from database 16 September 并且只更新了两个任务。在数据库中说 UPDATE 的末尾是注释行，它将最后一次同步更新到数据库。

您可以看到“数据库中的日期”是当前日期，但这是不可能的，因为它是在开始时从数据库中获取的，我手动将数据库中的日期更改为 9 月 16 日。
因此，它甚至在没有到达更新语句的情况下就更改了数据库，因此对于新日期，应用程序中没有任何内容需要更新。
//Taking the user info from the database
$userModel = new Application_Model_User();
$user = $userModel->findByEmail($data);
$userLastSync = $user[0]['sync_ts'];
echo "<br/>Date from database:".$userLastSync."<br>";
我完全困惑，我找不到为什么会这样
