PHP - How to set the timezone?

Question

Hi, I have written a PHP code for messages for each day.
https://code.sololearn.com/wDXv92qsPo5f/#php

The main part needs the timezone to display the correct day. For my code, I have set it like this:

// Time zone for right time
date_default_timezone_set('Asia/Dubai');

But as you can see, this is set to Asia timezone. Ppl in the USA or UK will not get the right message for the day. So how do I fix this timezone so that no matter which server location you are at, the time of day is right.

Thanx for reading

Answer 1

It's OK, Dubai is in Asia (http://php.net/manual/en/timezones.asia.php). You can try with the "Australia/Sydney" timezone to check the impact. For me it works.
For info, here the list of timezones: http://php.net/manual/en/class.datetimezone.php#datetimezone.constants.asia
