CURLOPT_CONNECTTIMEOUT と CURLOPT_TIMEOUT が検出されたときに、何かを検出、キャッチ、および実行したい。
これを行うにはどうすればよいですか?
次のヘッダーがあります。

$res は、html ファイル名を含む配列です。
public function multiCurl($res, $options = "") {
    if (count($res) <= 0)
        return False;
    $handles = array();
    if (!$options) // add default options
        $options = self::$options;
    // add curl options to each handle
    foreach ($res as $k => $row) {
        $ch{$k} = curl_init();
        $options[CURLOPT_URL] = $row['url'];
        curl_setopt_array($ch{$k}, $options);
        $handles[$k] = $ch{$k};
    }
    $mh = curl_multi_init();
    foreach ($handles as $k => $handle) {
        curl_multi_add_handle($mh, $handle);
    }
    $running_handles = null;
    //execute the handles
    do {
        $status_cme = curl_multi_exec($mh, $running_handles);
    } while ($cme == CURLM_CALL_MULTI_PERFORM);
    while ($running_handles && $status_cme == CURLM_OK) {

            do {
                $status_cme = curl_multi_exec($mh, $running_handles);
            } while ($status == CURLM_CALL_MULTI_PERFORM);
        }
    }
    foreach ($res as $k => $row) {
        $res[$k]['error'] = curl_error($handles[$k]);
        if (!empty($res[$k]['error']))
            $res[$k]['data'] = '';
        else {
            //$res[$k]['data'] = curl_multi_getcontent($handles[$k]);  // get results 
            file_put_contents(CRAWLER_FILES . $k . '.html', curl_multi_getcontent($handles[$k]));
        }
        // close current handler
        curl_multi_remove_handle($mh, $handles[$k]);
    }
    curl_multi_close($mh);
    return $res; // return response
}
