Folgende Konstanten werden von dieser Erweiterung definiert und stehen nur zur Verfügung, wenn die Erweiterung entweder statisch in PHP kompiliert oder dynamisch zur Laufzeit geladen wurde.
Beschreibungen und Funktionsweise dieser Konstanten sind unter curl_setopt() und curl_getinfo() verfügbar.
Beware of CURLE_* constants!
On the official site:
http://curl.haxx.se/libcurl/c/libcurl-errors.html
some constants are different, some missing compared to the PHP implementation.
Some examples:
in PHP the curl error number 28 is called
CURLE_OPERATION_TIMEOUTED
while in the official site is:
CURLE_OPERATION_TIMEDOUT
So if you use the second, it won't march the error 28 because in PHP it is not defined that way.
The same is for these:
CURLE_HTTP_RETURNED_ERROR
CURLE_UPLOAD_FAILED
CURLE_INTERFACE_FAILED
CURLE_SSL_CERTPROBLEM
CURLE_SEND_FAIL_REWIND
CURLE_LOGIN_DENIED
CURLE_AGAIN
that are in someway named differently or missing from PHP.
Note that CURLAUTH_NTLM refers specifically to NTLMv1 authentication. As of this writing, the cURL library does not yet support NTLMv2.
