How to Detect User Timezone in PHP?

To detect timezone, we can either set a timezone and display or we can directly display. Here, we will see two examples −

• Get and Display the default timezone.
• Set a Timezone and Display it.

Get the Default TimeZone

To get the default timezone in PHP, we will use the following method −

date_default_timezone_get(); 

Example

Let us see the example −

<?php
   echo "Default TimeZone: ";
   echo date_default_timezone_get();
?>

Output

Default TimeZone:UTC

Set a TimeZone and Display

In this example, we will first set a timezone using the following method −

date_default_timezone_set

To get the timezone we have set above, use the following method −

date_default_timezone_get(); 

Example

Let us now see the complete example −

<?php
   echo "Set Default TimeZone";
   date_default_timezone_set("Asia/Kolkata");
   echo "
Updated TimeZone: ";
   echo date_default_timezone_get();
?> 

Output

Set Default TimeZone:
Updated TimeZone: Asia/Kolkata
