How can network analysis tools like Firefox's RequestPolicy addon be integrated into PHP development for enhanced debugging capabilities?

Network analysis tools like Firefox's RequestPolicy addon can be integrated into PHP development for enhanced debugging capabilities by using PHP cURL to make HTTP requests and analyzing the response headers and content. By capturing and inspecting the network traffic within PHP scripts, developers can gain insights into the flow of data between their application and external resources.

// Example PHP script using cURL to make an HTTP request and analyze the response
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.example.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);

// Analyze response headers
$headers = curl_getinfo($ch);
print_r($headers);

// Analyze response content
echo $response;

curl_close($ch);
