To coder.ua[at]gmail.com:
Please note some errors have more than one constants:
[CURLE_FTP_PARTIAL_FILE]  18
[CURLE_PARTIAL_FILE]  18
[CURLE_HTTP_NOT_FOUND]  22
[CURLE_HTTP_RETURNED_ERROR]  22
[CURLE_OPERATION_TIMEDOUT]  28
[CURLE_OPERATION_TIMEOUTED]  28
[CURLE_BAD_DOWNLOAD_RESUME]  36
[CURLE_FTP_BAD_DOWNLOAD_RESUME]  36

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

/!\ ATTENTION if you are using curl multi handles
This function returns 0 in error conditions when run on curl handles accessed via curl_multi_info_read().
You must look at the data returned by curl_multi_info_read() for the true errno. The data is over there instead.

Gets a current list of all CURLE_* error constants, their applicable error messages, and their applicable error codes. Useful for making wrapper classes or for mapping cURL errors to specific Exception objects.
