php - Estimate traffic when using cURL -

i have page loads page in via curl. similar this:

function get_data($url) { $ch = curl_init(); $timeout = 5; curl_setopt($ch, curlopt_url, $url); curl_setopt($ch, curlopt_returntransfer, 1); curl_setopt($ch, curlopt_connecttimeout, $timeout); $data = curl_exec($ch); curl_close($ch); homecoming $data; } echo get_data($_get["url"]);

how can estimate amount of traffic of each request ? say, user wants display imdb.com @ page, want know how much of server's bandwidth used @ request (including images , css/js files passed).

its kinda simple actually

curl_getinfo($ch, curlinfo_size_download);
