Description:
------------
I was wondering why curl_errno() returned a 0 while beeing using with a curl_multi_init(). Not sure
if this is a bug or if it's a documentation issue so I stated it first as an documentation
issue.
It seems that the error is not populated into the resource. Only when I call curl_multi_info_read()
then it gets populated into the resource.

Test script:
---------------
$handles = [];
$urls = [
'https://www.google.com?v1',
'https://wwwgooglecom?v2',
'https://www.google.com?v3',
];
$mh = curl_multi_init();
foreach ($urls as $key => $value) {
$handles[$key] = curl_init($value);
curl_setopt($handles[$key], CURLOPT_HEADER, true);
curl_setopt($handles[$key], CURLOPT_TIMEOUT, 10);
curl_setopt($handles[$key], CURLOPT_RETURNTRANSFER, true);
curl_multi_add_handle($mh, $handles[$key]);
}
do {
$status = curl_multi_exec($mh, $running);
curl_multi_select($mh);
} while ($running > 0 && $status === CURLM_OK);
// while ($result = curl_multi_info_read($mh)) {} // <<< uncomment this will give you the
expected result
foreach($handles as $ch) {
echo "Handle: " . curl_errno($ch) . PHP_EOL;
}
Expected result:
----------------
$ php test.php
Result: (0)
Result: (6) Could not resolve: wwwgooglecom (Domain name not found)
Result: (0)
Actual result:
--------------
$ php test.php
Result: (0)
Result: (0)
Result: (0)
