HI

Here's what I'm trying to do: I have a php page I created on one domain, that stores information in a database. Next, I have another web page (This page is html NOT php) on a Different domain that I call this php page using Javascript, and would like to return a variable from the php page. How is this possible? I know it is, so don't say that it isn't!

In general you would do it like this:

Your php page:

$id = $_GET['id'];
//do some database query and fetch the array
//json_encode the array and echo
echo json_encode(array('id'=>$id, 'name'=>'test', 'descr'=>'test array from db'));

Your HTML page:

<html>
<head>
<script type="text/javascript">
xhttp = new XMLHttpRequest();
xhttp.open("GET", "http://example.com/script.php?id=1", false);
xhttp.send("");
response = xhttp.responseText;
var myArray = eval('(' + response + ')');

document.writeln(myArray.id);
document.writeln(myArray.name);
</script>
</head>
<body>
</body>
</html>
