How can PHP version compatibility impact the functionality of download scripts?

PHP version compatibility can impact the functionality of download scripts if the script uses functions or syntax that are not supported in older PHP versions. To solve this issue, developers should ensure that the script is compatible with the PHP version it will be running on by checking for deprecated functions or features and updating them to modern equivalents. 

// Check PHP version compatibility
if (version_compare(PHP_VERSION, '7.0.0', '<')) {
    die('This script requires PHP 7.0.0 or higher');
}

// Your download script code here
