What arrays need to be added to save cookies in "cookies.txt" using cURL in PHP?

To save cookies in "cookies.txt" using cURL in PHP, you need to set the CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR options with the path to the file where the cookies will be stored and retrieved from. This allows cURL to automatically handle the cookies for subsequent requests.

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://example.com");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt");

$response = curl_exec($ch);

curl_close($ch);
