What are the common pitfalls or errors that may arise when using cURL in PHP, especially on Windows systems?

One common issue when using cURL in PHP on Windows systems is the lack of proper SSL certificate verification, which can lead to security vulnerabilities. To solve this, you can specify the path to a CA bundle file that contains trusted certificates.

// Set the path to the CA bundle file
curl_setopt($ch, CURLOPT_CAINFO, 'C:/path/to/cacert.pem');
