How does the interaction between cURL and cookies work in PHP web development?

When using cURL in PHP web development, you may need to handle cookies for maintaining session information across multiple requests. To do this, you can use the CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR options in cURL to save and send cookies between requests. By specifying a file path for these options, cURL will automatically handle storing and sending cookies for you. 

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://example.com/login');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'username=myusername&password=mypassword');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');

$response = curl_exec($ch);

// Make subsequent requests with the same cURL handle to maintain session
curl_setopt($ch, CURLOPT_URL, 'https://example.com/profile');
$response_profile = curl_exec($ch);

curl_close($ch);
