CURLM_CALL_MULTI_PERFORM deprecated

Question

    do {
        $mrc = curl_multi_exec($mc, $active);
    } while ($mrc == CURLM_CALL_MULTI_PERFORM);

Answer 1

It's not really clear, if CURLM_CALL_MULTI_PERFORM is deprecated or not.

The symbol exists. A removal was not mentioned in the 7.27.0 Change Notes.

Like @tne pointed out in his comment: it seems reasonable to ignore it.
