Date/Time Functions
PHP Manual

timezone_version_get

Gets the version of the timezonedb

Description

string timezone_version_get()

Returns the current version of the timezonedb.

Parameters

This function has no parameters.

Return Values

Returns a string in the format YYYY.increment, such as 2022.2.

If you have a timezone database version that is old (for example, it doesn't show the current year), then you can update the timezone information by either upgrading your PHP version, or installing the » timezonedb PECL package.

Some Linux distributions patch PHP's date/time support to use an alternative source for timezone information. In which case this function will return 0.system. You are encouraged to install the » timezonedb PECL package in that case as well.

Examples

Example #1 Getting the timezonedb version

<?php
echo timezone_version_get();
?>

The above example will output something similar to:

2022.2
