How do you use php to communicate with App Inventors TinyWebDB component?


Google App Inventor has some information in their documentation for setting up a sample TinyWebDB webservice using python or app engine, however, I'm trying to use php. Is this possible? I've followed directions posted here but all I get is the error:

Communication with the web service encountered a protocol exception

I display this error in alabel component on the whenTinyWebDB1.WebServiceError block.

So here is what I have in my php files:


header('Cache-Control: no-cache, must-revalidate');
header('Expires: Mon, 26 Jul 2010 05:00:00 GMT');
header('Content-type: application/json');

$retval = array("VALUE", "tagged", '"'.time().'"'); 
echo json_encode($retval);

Which returns:



$tag = $_POST['tag'];
$value = $_POST['value'];
$retval = array("STORED", '"'.$tag.'"', '"'.$value.'"');
echo json_encode($retval);

Which returns:


Thanks for any suggestions or answers.




Instead of "setvalue", you should use "storeavalue"
