PHP 将时间与未定义的时区进行比较

发布于 2024-11-10 15:02:15 字数 683 浏览 0 评论 0原文

我需要比较时间，我使用变量来定义时区、当前时间和要比较的时间。

我正在使用此脚本根据用户选择执行某些操作。用户可以选择执行此操作的时间、日期和时区。

如果当前时间>或等于用户选择的这些操作应运行的时间。

所以我需要比较当前时间和用户选择的时间。当前时间由用户选择的时区给出。

这是我的代码。比较效果不太好。它认为与实际想法相反的事情......我需要帮助......可能不使用 php 5.3 或更高版本。如果版本 4 到 5 的功能都可用就更好了

date_default_timezone_set($TimeZone); //all the possible php timezones available can be choosen by the user
$todaydate = date('Y-m-d');
$time_now=mktime(date('G'),date('i'),date('s'));
$NowisTime=date('G:i:s',$time_now); //the time given by the selected timezone above
$time = $ris['Time']; //the time defined by the user in the DB
if($NowisTime >= $time){
DO THE ACTIONS
}else{
exit;

}

I need to compare times, I am using variables to define timezones, the current time and the time to be compared.

I am using this script to do certain actions based on what the user selects. The user can select a time when this action should be done, a date and a timezone.

If the current time is > or equal than the time selected by the user those action should run.

So I need to compare the current time and the time selected by the user. The current time is given by the timezone selected by the user.

This is the code I have. The comparison is not working fine. It thinks the oppposite thing than what should actually thinks... I need an help.. possibly not using php 5.3 or above. Better if functions are avaialbe from version 4 to 5

date_default_timezone_set($TimeZone); //all the possible php timezones available can be choosen by the user
$todaydate = date('Y-m-d');
$time_now=mktime(date('G'),date('i'),date('s'));
$NowisTime=date('G:i:s',$time_now); //the time given by the selected timezone above
$time = $ris['Time']; //the time defined by the user in the DB
if($NowisTime >= $time){
DO THE ACTIONS
}else{
exit;

}

数据库中的用户定义时间是否相对于同一时区。您可以尝试以下代码片段：

$dateTimeZone = new DateTimeZone("Asia/Chongqing");
$localTime = new DateTime("now", $dateTimeZone);
$definedTime = new DateTime("2011-05-29 10:00:00", $dateTimeZone);
if ($localTime >= $definedTime) {
    echo "It is about time.";
} else {
    // do nothing.
}

最好使用 Unix Time Stamp< 来保存用户定义的时间/a>.

If user defined time in database is relative to same timezone. you could try this snippet follow:

$dateTimeZone = new DateTimeZone("Asia/Chongqing");
$localTime = new DateTime("now", $dateTimeZone);
$definedTime = new DateTime("2011-05-29 10:00:00", $dateTimeZone);
if ($localTime >= $definedTime) {
    echo "It is about time.";
} else {
    // do nothing.
}

It would be better to save user defined time with Unix Time Stamp.
