What are the best practices for handling cookies in PHP when using Curl for web scraping or automation tasks?

When using Curl for web scraping or automation tasks in PHP, it is important to handle cookies properly to maintain session information and avoid being blocked by websites. The best practice is to store cookies in a separate file and reuse them in subsequent requests to maintain session state. This can be achieved by setting the CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR options in the Curl request. 

// Initialize Curl
$ch = curl_init();

// Set the URL to scrape
curl_setopt($ch, CURLOPT_URL, 'https://www.example.com');

// Set options to handle cookies
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies.txt');
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies.txt');

// Execute the Curl request
$response = curl_exec($ch);

// Close Curl
curl_close($ch);
