How can the PHP code be modified to handle cases where a "0" is returned as the HTTP code?

When a "0" is returned as the HTTP code, it usually indicates that the request was not successful or encountered an error. To handle this case in PHP, you can check if the HTTP code is "0" and then handle it accordingly, such as displaying an error message or logging the issue. This can help improve the error handling and user experience of your application. 

$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);

if ($http_code == 0) {
    echo "Error: HTTP code 0 returned. Please try again later.";
    // You can also log the error or perform other actions here
} else {
    // Handle successful HTTP response
}
