Just to let others who might be struggling to get it to work, curl_multi_info_read() doesn't work in PHP versions before 5.2.0, and instead returns NULL immediately.
curl_multi_info_read
(PHP 5, PHP 7, PHP 8)
curl_multi_info_read — Get information about the current transfers
Description
Ask the multi handle if there are any messages or information from the individual transfers. Messages may include information such as an error code from the transfer or just the fact that a transfer is completed.
Repeated calls to this function will return a new result each time, until a false is returned
as a signal that there is no more to get at this point. The integer pointed to with
queued_messages will contain the number of remaining messages after this
function was called.
Warning
The data the returned resource points to will not survive calling curl_multi_remove_handle().
Parameters
-
multi_handle -
A cURL multi handle returned by curl_multi_init().
-
queued_messages -
Number of messages that are still in the queue
Return Values
On success, returns an associative array for the message, false on failure.
| Key: | Value: |
|---|---|
msg |
The CURLMSG_DONE constant. Other return values
are currently not available. |
result |
One of the CURLE_* constants. If everything is
OK, the CURLE_OK will be the result. |
handle |
Resource of type curl indicates the handle which it concerns. |
Changelog
| Version | Description |
|---|---|
| 8.0.0 |
multi_handle expects a CurlMultiHandle
instance now; previously, a resource was expected.

Examples
Example #1 A curl_multi_info_read() example
<?php
$urls = array(
"http://www.cnn.com/",
"http://www.bbc.co.uk/",
"http://www.yahoo.com/"
);
$mh = curl_multi_init();
foreach ($urls as $i => $url) {
$conn[$i] = curl_init($url);
curl_setopt($conn[$i], CURLOPT_RETURNTRANSFER, 1);
curl_multi_add_handle($mh, $conn[$i]);
}
do {
$status = curl_multi_exec($mh, $active);
if ($active) {
curl_multi_select($mh);
}
while (false !== ($info = curl_multi_info_read($mh))) {
var_dump($info);
}
} while ($active && $status == CURLM_OK);
foreach ($urls as $i => $url) {
$res[$i] = curl_multi_getcontent($conn[$i]);
curl_close($conn[$i]);
}
var_dump(curl_multi_info_read($mh));
?>The above example will output something similar to:
array(3) {
["msg"]=>
int(1)
["result"]=>
int(0)
["handle"]=>
resource(5) of type (curl)
}
array(3) {
["msg"]=>
int(1)
["result"]=>
int(0)
["handle"]=>
resource(7) of type (curl)
}
array(3) {
["msg"]=>
int(1)
["result"]=>
int(0)
["handle"]=>
resource(6) of type (curl)
}
bool(false)
