Why is it important to update PHP versions beyond 5.3 and how does it affect script performance?

Updating PHP versions beyond 5.3 is important because older versions may contain security vulnerabilities and lack performance improvements present in newer versions. This can affect script performance by causing slower execution times and potential security risks. 

// Example code snippet to check PHP version and update if necessary
if (version_compare(PHP_VERSION, '5.3', '<')) {
    echo "Please update your PHP version to at least 5.3 for better performance and security.";
}
