PHP:根据用户的时区显示时间 [英] PHP: Show time based on user's timezone

问题描述

我想知道是否有办法在 php 中获取用户的时区，然后根据查看者的时区显示时间.我知道它可以在 javascript 中完成，但我想要一个在 php 中的解决方案.我搜索了很多，但找不到获得这项工作的方法.

I wonder if there is a way to get the timezone of the user in php and then display a time based on viewer's timezone. I know it can be done in javascript but i want a solution in php. I searched a lot but can't find a way to get this work.

所以基本上假设时间是 8:30 GMT+0530.它在印度时区，如果用户在纽约查看它，那么它应该是 21:30.

So basically suppose the time is 8:30 GMT+0530. Its in indian timezone i want if a user views this in Ne York then it should be 21:30 .

推荐答案

如果您在注册时添加了用户 Timezone 或者您以某种方式知道用户 Timezone，那么您可以试试这个...

If you added the users Timezone while registering or you know users Timezone somehow, then you can try this...

$users = [
    [
        'username' => 'foo',
        'timezone' => 'America/Los_Angeles'
    ],
    [
        'username' => 'bar',
        'timezone' => 'America/New_York'
    ]
];

foreach ($users as $user) {
    date_default_timezone_set($user['timezone']);
    echo $user['username'] . ' date and time is ' . date('Y-m-d H:i:s') . '<br />';
}

输出

foo time is 2013-02-28 18:13:49
bar time is 2013-02-28 21:13:49

您还可以在 JavaScrpt 中使用时区 在 JavaScript 中获取客户端的时区.发出 Ajax 请求并保存在 PHP 会话或数据库中.

You can also user Timezone in JavaScrpt Getting the client's timezone in JavaScript. Make an Ajax request and Save in PHP Session or database.
