How can a user ensure that their scripts are compatible with the latest PHP 5 version?

To ensure that scripts are compatible with the latest PHP 5 version, users should review the PHP manual for any deprecated features or functions that may have been removed in the latest version. They should also test their scripts on a development environment running the latest PHP version to identify any compatibility issues. Additionally, users can use tools like PHP_CodeSniffer to check for deprecated code and ensure compliance with the latest PHP standards.

// Example code snippet to check for deprecated code using PHP_CodeSniffer
