How can the functionality of saving cookies in "cookies.txt" be optimized in PHP?

To optimize the functionality of saving cookies in "cookies.txt" in PHP, you can use the `file_put_contents()` function to write the cookie data to the file. This function simplifies the process and ensures that the cookies are saved correctly. Additionally, you can use the `serialize()` function to serialize the cookie data before saving it to the file. 

// Serialize the cookie data
$cookie_data = serialize($_COOKIE);

// Save the serialized cookie data to "cookies.txt"
file_put_contents('cookies.txt', $cookie_data);
