Setting PHP's default timezone

In my web app, I let the users choose their preferred timezone from a list (that contains all timezones that PHP supports).

Let's say that $_POST['timezone'] is the chosen timezone (e.g. America/New_York). I set it with the following code which produces no errors:

default_date_timezone_set($_POST['timezone']);

But when I reload the page it goes back to what it was before (e.g. Europe/Moscow). Do I have to set the default timezone in every script or isn't the function (default_date_timezone_set) working properly? Thanks!

Set a cookie that contains the timezone the user chooses.

/// Make sure you sanitize all POST/COOKIE variables if needed.
$timezone = $_COOKIE['timezone'];

if(isset($_POST['timezone'])) {
    /// Set cookie for some amount of time -- I chose 2 weeks
    setcookie('timezone',$_POST['timezone'],time()+60*60*24*14);
    $timezone = $_POST['timezone'];
}

default_date_timezone_set($timezone);

This function changes the timezone for the execution of the script only. You could store the timezone in a session variable and set the time zone on top of every page.

You should save it in the database and set the timezone any time you do anything time related. It's working properly. It's only supposed to set it for that script execution (one HTTP request).
