How can PHP developers effectively handle HTTP status codes, timeouts, and SSL handshakes when accessing HTTPS sites via proxy servers?

When accessing HTTPS sites via proxy servers in PHP, developers can handle HTTP status codes, timeouts, and SSL handshakes effectively by using the cURL library. By setting appropriate cURL options such as CURLOPT_PROXY, CURLOPT_TIMEOUT, and CURLOPT_SSL_VERIFYPEER, developers can ensure that the requests are routed through the proxy server, have appropriate timeouts, and handle SSL certificates properly. 

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

// Set cURL options for proxy, timeout, and SSL verification
curl_setopt($ch, CURLOPT_PROXY, 'proxy_host:proxy_port');
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

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

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

// Check for errors
if(curl_errno($ch)){
    echo 'Curl error: ' . curl_error($ch);
}

// Close cURL session
curl_close($ch);

// Process the response
echo $response;
