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.

The manual above only mentions how to get an error description from the cURL handle ($ch) using curl_error():
<?php
$description = curl_error($ch);
?>

But you can also get a description from the error number itself using curl_strerror():
<?php
$description = curl_strerror(curl_errno($ch));
?>

The latter can be useful if you only have access to the error number but not to the cURL handle.

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.

<?php

$list   = get_defined_constants(TRUE);
$list   = preg_grep('/^CURLE_/', array_flip($list['curl']));
$result = array();

foreach ($list as $const) {
    $result[$const] = array
    (
        'code'    => constant($const),
        'message' => curl_strerror(constant($const))
    );
}

echo "<pre>";
echo print_r($result, TRUE);
echo "</pre>";
