How can the use of deprecated PHP features be identified and updated to comply with current standards?

Identifying deprecated PHP features can be done by enabling error reporting and checking for any deprecated function calls or features in your code. To update to comply with current standards, replace deprecated functions with their recommended alternatives or refactor the code to use modern PHP features. 

// Enable error reporting to display deprecated warnings
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Check for deprecated function calls in your code
