How can the use of conditional statements based on PHP version improve script compatibility and functionality?

When writing PHP scripts, it's important to consider the version compatibility of the PHP interpreter that will run the script. By using conditional statements based on the PHP version, you can ensure that your script will work correctly on different PHP versions. This can help improve script compatibility and functionality by allowing you to use features that are only available in certain PHP versions, or by providing alternative code paths for older PHP versions. 

if (version_compare(PHP_VERSION, '7.0.0', '>=')) {
    // Code that will only run on PHP 7.0.0 or newer
} else {
    // Code that will run on older PHP versions
}
