PHP: Show time based on user's timezone

Question

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.

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 .

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 />';
}

Output

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

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.

This is so static and useless, you must get the user's informations and set the timezone by them – Sam Mar 01 '13 at 02:21

It's static for the purpose of demonstration. Of course you don't write your users into an array. – Timothy Owen Sep 20 '13 at 21:37

You must get the user information and set the default timezone

Look date_default_timezone_set()

And ip geolocation api

What if their API doesn't have a user's IP in their db? JS will **always** return the user's timezone. PHP cannot. Also, doing it like this is not reliable, due to VPN's like iPredator etc. – Danny Beckett Mar 01 '13 at 02:10
In that case you can try with a generic timezone, like $_SERVER['HTTP_ACCEPT_LANGUAGE'] – Sam Mar 01 '13 at 02:13
Why use a generic timezone when you can use the user's actual timezone, provided by JS? – Danny Beckett Mar 01 '13 at 02:14

And if an user have the js disabled? :P – Sam Mar 01 '13 at 02:14
Then they probably don't wanna see this kinda crap anyway :p – Danny Beckett Mar 01 '13 at 02:17

You can get the users timezone by crossing their IP with many available geolocation databases, such as IPInfoDB

http://ipinfodb.com/ip_location_api.php

you will need to register for a free API key, but they also provide you with a working example(above)
