In this article, we will explore how to use it in your PHP applications.

This function does not take any arguments. When you call this function, it returns a string that represents the version of the timezone database that PHP is currently using. The returned string contains just the version number, such as 2023.3 or 2024.1.

Usage

To use the timezone_version_get() function in your PHP applications, follow these steps:

1. Call timezone_version_get() to retrieve the version string.
2. Store or display the returned value.
3. Use the version information to verify that your application relies on an up-to-date timezone database.

Example
