PHP cURL Warning during curl_multi_add_handle

Question

My php code

    $urlArray = array('http://firsturl.com', 'http://secondurl.com');
    $nodeCount = count($urlArray);
    $chContainter = array();
    $mh = curl_multi_init();
    for($i = 0; $i < $nodeCount; $i++) {
        $chContainter[$i] = curl_init();
        curl_setopt($chContainter[$i], CURLOPT_URL, $urlArray[$i]);
        curl_setopt($chContainter[$i], CURLOPT_HEADER, 0);
        curl_setopt($chContainter[$i], CURLOPT_RETURNTRANSFER,1);
        curl_multi_add_handle($mh,$chContainter[$i]);
    } 

generates the following warning

Warning: (null) (): 4 is invalid Resource descriptor cURL in Unknown on line 0

Warning: (null) (): 5 invalid Resource descriptor cURL in Unknown on line 0

I did some debugging and found out that a warning was generated when I try to add the curl handle to $ mh.

Please, help. Thank.
