未在datepiker中选择的事件日期和时间小于服务器时间 - Event date and time not select in datepiker less then server time

Event date and time not select in datepiker less then server time

用户使用bootstrep datepiker护理节日活动

用户先选择日期和时间，然后选择时间4.如果用户选择日期事件时间为04-09-14 11:55AM，服务器时间为04-09-14 11:60AM在创建事件的无效日期之后。

我正在使用此代码。

    $event_time =htmlentities($_REQUEST['date_piker']) ;
    $server_time    = htmlentities( date('m-d-y h:iA')) ;
    echo 'Event time:-&nbsp;&nbsp;'. $event_time.'</br>';
    echo 'Server Time:-'. $server_time;

    if($event_time < $server_time)
    {
        echo 'Date and time is invalid';
    }
    else
    {
       echo 'Date and time is valid'; 
    }

但它不起作用。我需要帮助。

您应该使用DateTime:：createFromFormat

$event = DateTime::createFromFormat('m-d-y h:iA', '04-09-14 11:55AM');
$server = DateTime::createFromFormat('m-d-y h:iA', '04-09-14 11:00AM');
if($event < $server){
    echo 'Date and time is invalid';
}else{
    echo 'Date and time is valid'; 
}

为什么不使用时间戳？像这个

<?php
$event_time = htmlentities($_REQUEST['date_piker']);
$eventTimeTimestamp = strtotime($event_time);
$serverTimeTimestamp = time();
$server_time = htmlentities(date('m-d-y h:iA', $serverTimeTimestamp));
echo 'Event time:-&nbsp;&nbsp;' . $event_time . '</br>';
echo 'Server Time:-' . $server_time;
if ($eventTimeTimestamp < $serverTimeTimestamp) {
    echo 'Date and time is invalid';
} else {
    echo 'Date and time is valid';
}
