// Load the User truncate library require_once('user_truncate.php'); // Truncate a user name to 10 characters $user_name = 'john123'; $truncated_name = UserTruncate::truncate($user_name, 10); echo $truncated_name;In this example, the User truncate library is loaded using the `require_once` function. The `UserTruncate` class is used to truncate a user name to 10 characters using the `truncate` method. The truncated user name is then displayed using `echo`. The package library for the User truncate app in PHP may vary, depending on the developer who created it. However, it is likely that this app may be included in a larger utility library that contains other PHP functions for working with user data.
