How can PHP version compatibility impact the functionality of file manipulation functions like rename()?

PHP version compatibility can impact the functionality of file manipulation functions like rename() because the behavior and arguments of these functions may change between different PHP versions. To ensure compatibility across different PHP versions, it is recommended to check the PHP version before using these functions and provide fallback solutions if needed. 

// Check PHP version before using rename()
if (version_compare(PHP_VERSION, '7.2.0') >= 0) {
    // Use rename() function
    rename($oldfile, $newfile);
} else {
    // Use alternative method for renaming files
    if (copy($oldfile, $newfile)) {
        unlink($oldfile);
    }
}
