This code segment is from http://blockchain.info/api/blockchain_wallet_api How do i execute this? what do i need to install, do i need to link to a json library or something. I need a step thru process here. Thanks <?
$guid="GUID_HERE";
$firstpassword="PASSWORD_HERE";
$secondpassword="PASSWORD_HERE";
$amounta = "10000000";
$amountb = "400000";
$addressa = "1A8JiWcwvpY7tAopUkSnGuEYHmzGYfZPiq";
$addressb = "1ExD2je6UNxL5oSu6iPUhn9Ta7UrN8bjBy";
$recipients = urlencode('{
"'.$addressa.'": '.$amounta.',
"'.$addressb.'": '.$amountb.'
}');
$json_url = "http://blockchain.info/merchant/$guid/sendmany?password=$firstpassword&second_password=$secondpassword&recipients=$recipients";
$json_data = file_get_contents($json_url);
$json_feed = json_decode($json_data);
$message = $json_feed->message;
$txid = $json_feed->tx_hash;
?>

I think it would be more efficient for you to answer, what errors are you experiencing?
The json module seems to be enabled by default in recent PHP versions. The only other dependency is on the http file wrapper being enabled, in the file_get_contents call. What is the output of var_dump(stream_get_wrappers()) ?

Here's a practical example with php/MySQL. Lets say for the sake of argument you have a MySQL database table like this: CREATE TABLE `bitcoin_payments` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`bitcoin_address` varchar(34) NOT NULL,
`payment_in_satoshi` bigint(20) unsigned NOT NULL DEFAULT '0',
`transaction_hash` varchar(64) NOT NULL,
PRIMARY KEY (`id`)
); And in this table you have a list of payments to be made. If the payment has already been made then the transaction_hash field contains the transaction hash the payment was made with, otherwise it's empty. <?php
$guid="GUID_HERE";
$firstpassword="PASSWORD_HERE";
$secondpassword="PASSWORD_HERE";
// Your MySQL database login credentials here
$host="localhost"; // MySQL host
$user=""; // MySQL user
$pass=""; // MySQL password for user above
$db=""; // MySQL database to use
mysql_select_db($db, mysql_connect($host, $user, $pass));
$result=mysql_query("SELECT `id`, `bitcoin_address`, `payment_in_satoshi` FROM `bitcoin_payments` WHERE `transaction_hash`='' ORDER BY `id` ASC");
$recipient_list=array();
$new_paid_ids="";
if(mysql_num_rows($result)>0)
{
while($row=mysql_fetch_assoc($result))
{
$new_paid_ids.=$row["id"].",";
$recipient_list[$row["bitcoin_address"]]=$row["payment_in_satoshi"];
}
$new_paid_ids=trim($new_paid_ids, ",");
}
if(count($recipient_list)>0)
{
$recipients=urlencode(json_encode($recipient_list));
$json_url = "http://blockchain.info/merchant/$guid/sendmany?password=$firstpassword&second_password=$secondpassword&recipients=$recipients";
$json_data = file_get_contents($json_url);
if($http_response_header[0]=="HTTP/1.1 200 OK")
{
$json_feed = json_decode($json_data);
$error = $json_feed->error;
if(is_null($error))
{
$message = $json_feed->message;
$txid = $json_feed->tx_hash;
mysql_query("UPDATE `bitcoin_address` SET `transaction_hash`='".mysql_real_escape_string($txid)."' WHERE `id` IN(".$new_paid_ids.")");
echo $message." - <a href='https://blockchain.info/tx/".$txid."'>".$txid."</a>";
}
else
echo $error;
}
else
echo "bitchain.info returned the following http error:<br /><br />".$http_response_header[0];
}
?> ;)

how do you send the data

The data is sent in the file_get_contents() line. (Line 31 in the example above). It's the equivalent of you opening the url stored in the variable $json_url in your Web browser. Assuming you get a 200 response and no error is returned, the funds will have been sent at this point.
