PHP-php中curl的问题!

Question

现在用curl去抓取网页，当抓取成功以后如何获得抓取这个过程所耗费的时间呢？

Answer 1

传输所消耗的时间

$url = 'http://www.net.com/pages/home.aspx';

$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $url);
$response = curl_exec($ch);

$total_time = curl_getinfo($ch, CURLINFO_TOTAL_TIME);
var_dump($total_time);
curl_close($ch);
