(PHP 5 >= 5.3.0, PHP 7, PHP 8)
timezone_version_get — Gets the version of the timezonedb
This function has no parameters.
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.
Example #1 Getting the timezonedb version
<?php
echo timezone_version_get();
?>The above example will output something similar to:
2022.2
