How can one determine if a PHP resource, such as a book or website, is up-to-date and relevant to current PHP versions?

To determine if a PHP resource is up-to-date and relevant to current PHP versions, one can check the publication date of a book or the last update date of a website. Additionally, it is important to look for information on the PHP version compatibility within the resource itself or reviews from users who have tested it with the latest PHP versions. 

// Example code snippet to check PHP version compatibility
if (version_compare(PHP_VERSION, '7.4', '<')) {
    echo 'This resource may not be fully compatible with your current PHP version.';
} else {
    echo 'This resource is compatible with your current PHP version.';
}
