What are common challenges when using cURL to handle cookies in PHP?

One common challenge when using cURL to handle cookies in PHP is that cookies need to be manually managed in the cURL requests, which can be cumbersome and error-prone. To solve this, you can use the CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR options to automatically handle cookies in cURL requests.

// Initialize cURL session
$ch = curl_init();

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

// Enable cookie handling
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');

// Execute the cURL session
$response = curl_exec($ch);

// Close cURL session
curl_close($ch);
