CURL_MULTI_INFO_READ(3) 						 1						   CURL_MULTI_INFO_READ(3)

curl_multi_info_read - Get information about the current transfers

SYNOPSIS
       array curl_multi_info_read NULL (resource  $mh, [int  &$msgs_in_queue])

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 $msgs_in_queue 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(3).

PARAMETERS
	      o $mh
		-A cURL multi handle returned by curl_multi_init(3).

	      o $msgs_in_queue
		- Number of messages that are still in the queue

RETURN VALUES
	On success, returns an associative array for the message, FALSE on failure.

       Contents of the returned array

EXAMPLES
       Example #1

	      A curl_multi_info_read(3) 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)
