Description:
------------
Hello! 

I am writing a php-cgi server, using curl-multi.  It needs to start a bunch of curl  'threads', and steadily process the results of finished 'threads' and start new ones in  their place.   

It seems to be working other than curl_multi_info_read() - this function does not  return any data so I cannot see which curl threads have finished and are ready for  processing.   

Looking at the curl.haxx.se curl-lib docs, it doesn't look too complicated (I'm not a C  programmer though!) to implement, seeing as everything else is working.  Perhaps I  have missed something entirely.   

I assume it is the same problem as mentioned here:? 

http://marc.theaimsgroup.com/?l=php-dev&m=104791992407964&w=2 

Thank you in advance for any help or suggestions you can offer, or perhaps even an  ETA on when this function might be finished so I can either wait, or skin the cat  another way. 

Warm regards, 

Jason 


Reproduce code:
---------------
$status_of_ch_threads = curl_multi_info_read();

Expected result:
----------------
Have the status returned

Seeing this on php 5.05 on windows.  Basically from the code (5.05) it looks like curl_multi_info_read *should* return an array so one can determine the state of the requests.  However this function doesn't return anything.  

I've included my test wrapper which does work outside the call to info_read.

Not supporing this function really cripples the usefulness of more sophisticated programs that use curl_multi.

<?php

#-- Array of stuff
$connomains = array(
   "http://www.cnn.com/",
   "http://www.canada.com/",
   "http://www.yahoo.com/",
   "http://www.google.com/",
   "http://www.popmonkey.com/"
   );

#-- Initalize our multiple request
$mh = curl_multi_init();

#-- Setup each handle
foreach ($connomains as $i => $url) {
       $conn[$i]=curl_init($url);
       curl_setopt($conn[$i],CURLOPT_RETURNTRANSFER,1);
       curl_multi_add_handle ($mh,$conn[$i]);
}

#-- Perform the request
$lastactive = 5;
do {
  $n=curl_multi_exec($mh,$active);
  if( $active != $lastactive )  {
    $lastactive = $active;
    print_r( curl_multi_info_read( $mh ) );
    print "Left: $active \n";
  }
} while ($active);

foreach ($connomains as $i => $url) {
       $res[$i]=curl_multi_getcontent($conn[$i]);
       curl_close($conn[$i]);
}

#print_r($res);

?>
