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.

Regarding CURLE_OPERATION_TIMEDOUT vs. CURLE_OPERATION_TIMEOUTED:

Originally cURL had the constant named TIMEOUTED (read: "timeout-ed"). This was changed[1] in 2007 and v7.17.0 to be TIMEDOUT (read: "timed out") and the old constant kept in place as an alias.

PHP started off using TIMEOUTED as well. The TIMEDOUT constant was added[2] in 2012 and v5.5.0 and the old constant was *kept in place*.

If you ask me, the TIMEDOUT constant reads more nicely (not to mention is technically the correct one to use) and as long as you're using PHP 5.5+ then it is available. If you have to support older versions then I suggest you keep using the new constant and add a polyfill like

<?php
if (version_compare(PHP_VERSION"5.5.0""<")) {
   
define("CURLE_OPERATION_TIMEDOUT"CURLE_OPERATION_TIMEOUTED);
}
?>

or

<?php
// PHP <5.5.0
defined("CURLE_OPERATION_TIMEDOUT") || define("CURLE_OPERATION_TIMEDOUT"CURLE_OPERATION_TIMEOUTED);
?>

to be removed once you stop supporting them.

In PHP version 7.1.11 there is also constants for HTTP/2 :
CURL_VERSION_HTTP2 = 65536 (1 << 16)
CURL_HTTP_VERSION_2_0 = 3

I don't know the first version of PHP that defines it.
