Send to Multiple addresses using Blockchain.info

[BitCoinDream]

Does the following code works ?

Code:

<?php

$guid="blochain-info-wallet-id";
$firstpassword="blockchain-info-wallet-password";

$amounta = "10000";
$amountb = "40000";
$addressa = "1A8JiWcwvpY7tAopUkSnGuEYHmzGYfZPiq";
$addressb = "1ExD2je6UNxL5oSu6iPUhn9Ta7UrN8bjBy";
$recipients = urlencode('{
                  "'.$addressa.'": '.$amounta.',
                  "'.$addressb.'": '.$amountb.'
               }');

$note = "Payment Note"

$json_url = "http://blockchain.info/merchant/$guid/sendmany?password=$firstpassword&recipients=$recipients&note=$note";

$json_data = file_get_contents($json_url);

$json_feed = json_decode($json_data);

$message = $json_feed->message;
$txid = $json_feed->tx_hash;

echo "Message: ".$message."<br /><br />Tx ID: ".$txid;

?>

I tried with both http & https, but neither is working !!!
