Description:
------------
http_get is supposed to return false on connection timeout, but instead it returns an empty string.

Library version according to php.exe --re http:


http version 1.6.1-dev

Reproduce code:
---------------
if (false === ($http = http_get('http://0.0.0.0/', array('timeout' =>
15, 'connecttimeout' => 15)))) {
  echo 'FALSE returned';
}
else {
  var_dump($http);
}

Expected result:
----------------
FALSE returned

Actual result:
--------------
string(0) ""

Thank you for taking the time to write to us, but this is not
a bug.

FALSE is only returned on "hard" failures like parsing parameters or building the request.  As soon as it comes to execute the request the return value will be the response, i.e. on any serious connect/transfer failure an empty string resp. a partially received response.

Thanks.

Thanks for your response. If this is the intended behavior, would you please document this in the official manual so developers are at least aware of it?

How then can I detect a timeout? Should I compare total_time to my timeout value? Is this guaranteed to be > on timeout and <= on completion? Do I need to examine the error string?
