   8 Just a quick info, because I forget this again and again -- and it's not noted
   9 in the [documentation](http://php.net/manual/en/ref.http.php) yet either.

  11 Sub-second timeouts are supported by [libcurl](http://curl.haxx.se/libcurl/)
  12 and thus by [pecl_http](http://pecl.php.net/pecl_http) -- yes but only if
  13 libcurl is built with [(c-)ares](http://c-ares.haxx.se) support:

  15 &lt;quote url="[curl_easy_setopt.html](http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTTIMEOUTMS)">

  17 > If libcurl is built to use the standard system name resolver, that portion
  18 of the transfer will still use full-second resolution for timeouts with a
  19 minimum timeout allowed of one second.
