Are there best practices or guidelines for maintaining anonymity when using Curl to access websites?

When using Curl to access websites while maintaining anonymity, it's important to set certain options such as user-agent, referer, and proxy settings to avoid revealing your identity. Additionally, using HTTPS connections and rotating proxies can further enhance anonymity.

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.example.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3');
curl_setopt($ch, CURLOPT_REFERER, 'https://www.google.com');
curl_setopt($ch, CURLOPT_PROXY, 'http://proxy.example.com:8080');
curl_setopt($ch, CURLOPT_PROXYUSERPWD, 'username:password');
$response = curl_exec($ch);
curl_close($ch);
