curl question

hi Guys
I have this following code which actually tries to get content of three website with curl

Code:

$nodes = array(
            'http://localhost:8080/ngbdcart/index.php/checkout_shipping/run_carrier/run',
            'www.microsoft.com',
            'www.newgenbd.net'
        );
        $node_count = count($nodes);

        $curl_arr = array();
        $master = curl_multi_init();

        for ($i = 0; $i < $node_count; $i++) {
            $url = $nodes[$i];
            $curl_arr[$i] = curl_init($url);
            curl_setopt($curl_arr[$i], CURLOPT_HEADER, 0);
            curl_setopt($curl_arr[$i], CURLOPT_RETURNTRANSFER, true);
            curl_setopt($curl_arr[$i], CURLOPT_TIMEOUT, 30);
            curl_multi_add_handle($master, $curl_arr[$i]);
        }
        $running = NULL;
        do {
            curl_multi_exec($master, $running);
            usleep (250000);
        } while ($running > 0);

        echo "results: <br/>";
        for ($i = 0; $i < $node_count; $i++) {
            $results = curl_multi_getcontent($curl_arr[$i]);
            echo $results;
            curl_multi_remove_handle($master,$curl_arr[$i]);
        }
        curl_multi_close($master);
        echo 'done';

the problem is the i get output from last two urls in the $nodes array...but for the locahost.. one i get response randomly...
and the run() function is a very simple it just echos one word "Helloooo"

anyone knows how to solve this problem???
Thanks in advance
