Can PHP be used to construct a complete HTTP package?

Yes, PHP can be used to construct a complete HTTP package by utilizing the built-in cURL extension. cURL allows you to send HTTP requests, handle responses, and interact with various web services. By using cURL functions in PHP, you can create a complete HTTP package to make requests, handle responses, set headers, and more. 

// Initialize cURL session
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, 'http://example.com/api');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute cURL session
$response = curl_exec($ch);

// Close cURL session
curl_close($ch);

// Handle response
if ($response) {
    echo $response;
} else {
    echo 'Error: ' . curl_error($ch);
}
