How Can I Easily Convert Date and Time Between Time Zones in PHP?

Converting Date and Time across Time Zones in PHP

Converting date and time between different time zones is a common task in PHP. Here's an effortless approach to achieve this:

Using DateTime Objects or Aliases

Utilize DateTime objects or their function aliases to convert date and time. For instance:

date_default_timezone_set('Europe/London');

$datetime = new DateTime('2008-08-03 12:35:23');
echo $datetime->format('Y-m-d H:i:s') . "\n";

$la_time = new DateTimeZone('America/Los_Angeles');
$datetime->setTimezone($la_time);
echo $datetime->format('Y-m-d H:i:s');

Dynamic Time Zone Conversion for User-Specific Displays

If users log in from diverse locations, you can dynamically determine their time zones. Upon user login, set the time zone for your DateTime object accordingly. Store time in a single time zone in the database and convert to the desired time zone when querying using the appropriate method.
