What best practices should be followed when working with cookies in PHP using cURL?

When working with cookies in PHP using cURL, it is important to ensure that the cookies are properly managed and maintained throughout the request/response cycle. This includes setting the CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR options to specify the file where cookies should be stored and read from. Additionally, it is recommended to use the CURLOPT_COOKIESESSION option to start a new session and ignore any existing cookies. 

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies.txt');
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies.txt');
curl_setopt($ch, CURLOPT_COOKIESESSION, true);

$response = curl_exec($ch);

if($response === false){
    echo 'Curl error: ' . curl_error($ch);
}

curl_close($ch);
?>
