我如何知道curl_multi_exec（）中的单个请求何时在PHP中完成？

Question

I would like to time my individual requests. They were timed before as separate curl requests. Now I would like to combine them with curl_multi_exec and continue to time how long they take. Here is my code:

$mh = curl_multi_init();
curl_multi_add_handle($mh, $ebayRequest);
curl_multi_add_handle($mh, $prosperentRequest);
$running = null;
do {
    curl_multi_exec($mh, $running);
    curl_multi_select($mh);
} while ($running > 0);
$ebay = curl_multi_getcontent($ebayRequest);
$prosperent = curl_multi_getcontent($prosperentRequest);
//close the handles
curl_multi_remove_handle($mh, $ebayRequest); 
curl_multi_remove_handle($mh, $prosperentRequest);
curl_multi_close($mh);

Here is the old code which timed them.

$ebayTime = microtime(true);
// $ebay = $this->ebayExecuteSearch($ebay);
Yii::warning("Ebay time: ".(microtime(true) - $ebayTime));

I thought curl_multi_info_read might help, but it doesn't look useful.
