What are the potential pitfalls of not updating PHP versions and how can it affect the functionality of SimpleXML?

Potential pitfalls of not updating PHP versions include security vulnerabilities, compatibility issues with newer libraries and frameworks, and lack of support for newer features and improvements. This can affect the functionality of SimpleXML by potentially exposing the application to security risks and preventing it from taking advantage of performance enhancements and bug fixes. To solve this issue, it is recommended to regularly update PHP to the latest stable version to ensure the security and stability of the application. 

// Check the current PHP version
if (version_compare(PHP_VERSION, '7.4.0') < 0) {
    echo "Please update PHP to version 7.4.0 or higher";
    exit;
}
