curl_multi_info_read — Get information about the current transfers
$mh
   [, int &$msgs_in_queue = NULL
  ] )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 
   msgs_in_queue will contain the number of remaining messages after this 
   function was called.
  
The data the returned resource points to will not survive calling curl_multi_remove_handle().
mh
A cURL multi handle returned by curl_multi_init().
msgs_in_queueNumber of messages that are still in the queue
   On success, returns an associative array for the message, FALSE on failure.
  
| Key: | Value: | 
|---|---|
| msg | The CURLMSG_DONEconstant. Other return values
       are currently not available. | 
| result | One of the CURLE_*constants. If everything is
       OK, theCURLE_OKwill be the result. | 
| handle | Resource of type curl indicates the handle which it concerns. | 
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);
    $info = curl_multi_info_read($mh);
    if (false !== $info) {
        var_dump($info);
    }
} while ($status === CURLM_CALL_MULTI_PERFORM || $active);
foreach ($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)
