How important is it to update PHP for security reasons, even if it's only used locally?

It is important to update PHP for security reasons, even if it's only used locally, as outdated versions may contain vulnerabilities that could be exploited by attackers. Regular updates ensure that your PHP environment is secure and protected from potential threats, regardless of whether it is used locally or online. 

<?php
// Check for PHP updates and install if necessary
if (version_compare(PHP_VERSION, '7.4.0') < 0) {
    echo "Please update PHP to version 7.4 or higher for security reasons.";
}
?>
