如何比较cakephp4中的日期时间

如何解决如何比较cakephp4中的日期时间

我正在使用以下代码来比较 DB DateTime 和输入字段 DateTime 是否相等但它不起作用，请帮我解决这个问题-

$appointment_time = $this->Appointments->find()->select(['appointment_time']);
$appointment_time1 = $this->request->getData('appointment_time');
$dt = ($appointment_time == $appointment_time1);

解决方法

始终尝试对变量使用 debug() 函数以了解差异。

debug($appointment_time1);
debug($appointments);

就您而言，$appointment_time 不是您所期望的，而是 \Cake\ORM\Query 对象。而 $appointment_time1 是一个字符串。

尝试：

// convert posted string to date time format
$appointment_time1 = date('Y-m-d H:i:s',strtotime($this->getRequest()->getData('datetime')));

// fetch data from db
$appointments = $this->Appointments->find()->select(['appointment_time']);

foreach ($appointments as $appointment) {
   echo $appointment->appointment_time->format('Y-m-d H:i:s') == $appointment_time1 ? 'OK' : 'NOT OK';
}

或

$appointment = $this->Appointments->find()->select(['appointment_time'])->first();

echo $appointment->appointment_time->format('Y-m-d H:i:s') == $appointment_time1 ? 'OK' : 'NOT OK';

也试试：

$appointment->appointment_time->getTimestamp() == strtotime($this->getRequest()->getData('datetime'));
