I have been trying to run a PHP program to send json data using the post. I am enclosing the code below.

The error I am receiving is
"Warning: file_get_contents(https://rest.netsuite.com/app/site/hosting/restlet.nl?script=1&deploy=1) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request in /Library/WebServer/Documents/testpost2.php on line 9
An error occured while trying to save record."

Thanks ....

<?php
/**Host is the external URL found in the RESTlet deployment page */

$host ="https://rest.netsuite.com/app/site/hosting/restlet.nl?script=1&deploy=1";
$context = makeContext();


$response = file_get_contents($host, false, $context);
