How can the use of cURL error handling functions like curl_error improve troubleshooting for JSON calls in PHP?

When making JSON calls in PHP using cURL, errors can occur due to various reasons such as network issues or server problems. By using cURL error handling functions like curl_error, we can retrieve the error message if the JSON call fails. This can help in troubleshooting the issue and providing more detailed information about what went wrong during the JSON call. 

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.example.com/data.json");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

if($response === false){
    echo "cURL Error: " . curl_error($ch);
} else {
    // Process the JSON response
    $data = json_decode($response, true);
    // Further processing of the data
}

curl_close($ch);
