How can the use of Firebug help in troubleshooting issues with PHP scripts on external servers?

Firebug can be used to inspect network requests and responses, including those made to external servers from PHP scripts. By using Firebug, developers can identify any errors or issues with the server responses, such as incorrect data being returned or unexpected behavior. This can help in troubleshooting and fixing problems with PHP scripts that rely on external server interactions.

// Example PHP code snippet using cURL to make a request to an external server
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.example.com/data');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

// Check for errors in the response
if (!$response) {
    echo "Error fetching data from external server";
} else {
    // Process the response data
    $data = json_decode($response, true);
    // Additional code to handle the data as needed
}
