Note that you can detect errors using curl_multi_info_read() in the curl_multi_exec() loop that don't show up later using curl_errno(). This seems particularly true of connection errors.

you should look on http://php.net/manual/en/curl.constants.php for the error codes, not on the linked official curl doc. some of the error codes are different, at least the one mentioned on the other page:
in PHP the curl error number 28 is called
CURLE_OPERATION_TIMEOUTED
while in the official site is:
CURLE_OPERATION_TIMEDOUT

The error codes come directly from the curl source code. Specifically, look at the curl.h file and it will tell you exactly what each returned code does.
Most of these codes are cryptic but at least you can get a clue as to what the errors are.
Here is a quick snippet of what the errors in the curl.h look like:
CURLE_OK = 0,
CURLE_UNSUPPORTED_PROTOCOL, /* 1 */
CURLE_FAILED_INIT, /* 2 */
CURLE_URL_MALFORMAT, /* 3 */
CURLE_URL_MALFORMAT_USER, /* 4 - NOT USED */
CURLE_COULDNT_RESOLVE_PROXY, /* 5 */
CURLE_COULDNT_RESOLVE_HOST, /* 6 */
CURLE_COULDNT_CONNECT, /* 7 */
CURLE_FTP_WEIRD_SERVER_REPLY, /* 8 */
Note that code 0 means its not an error, it means success.
