What are the recommended tools or methods for monitoring network traffic in PHP applications?

Monitoring network traffic in PHP applications can be crucial for debugging, performance optimization, and security purposes. One recommended tool for monitoring network traffic in PHP applications is Wireshark, a popular network protocol analyzer. Another method is to use PHP libraries such as Guzzle or cURL to log and analyze HTTP requests and responses within your application. 

// Example using Guzzle to monitor network traffic
use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;
use GuzzleHttp\Middleware;

// Create a new Guzzle client with a custom handler stack
$client = new Client([
    'handler' => HandlerStack::create(),
]);

// Add a middleware to the handler stack to log requests and responses
$history = Middleware::history($container);
$client->getConfig('handler')->push($history);

// Make a request using the Guzzle client
$response = $client->get('https://www.example.com');

// Access the recorded requests and responses from the history container
foreach ($container as $transaction) {
    echo $transaction['request']->getMethod() . ' ' . $transaction['request']->getUri() . "\n";
    echo $transaction['response']->getStatusCode() . "\n";
}
