How can PHP developers ensure their code is future-proof when using PHP version-specific functions?

PHP developers can ensure their code is future-proof when using PHP version-specific functions by checking the PHP version before using those functions. This can be done by utilizing the `PHP_VERSION` constant and comparing it to the minimum required version for the function. If the PHP version is lower than the required version, developers can implement a fallback or alternative solution to maintain compatibility across different PHP versions. 

if (version_compare(PHP_VERSION, '7.2.0') < 0) {
    // Fallback or alternative solution for PHP versions below 7.2.0
} else {
    // Code that uses PHP version-specific functions for PHP 7.2.0 and above
}
