timezone_version_get Gets the version of the timezonedb &reftitle.description; stringtimezone_version_get Returns the current version of the timezonedb. &reftitle.parameters; &no.function.parameters; &reftitle.returnvalues; 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. &reftitle.examples; &example.outputs.similar; &reftitle.seealso; List of Supported Timezones
