First you have to create your client script. We’ll include the jQuery librry and we’ll create a standard ajax request:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
	$.ajax({
		error: function(jqXHR,textStatus,errorThrown){alert(textStatus+' '+errorThrown)},
		url: "http://www.yourdomain.com/json.php",
		success: function(data){alert(data)},
		dataType: 'json',
		data: {}
	});
</script>

Now you will most likely get the following error:

	Origin http://www.yourdomain.com is not allowed by Access-Control-Allow-Origin.

So it’s time to set your server the right way:
If your are using something like this:

	<?php
		echo json_encode(array('a','r','r','a','y'));
	?>

it will not work. You have to specify Access-Control-Allow-Origin access. You can enable it for one site, or you can give access to all websites. Here’s how to do it:

	<?php
		header('Access-Control-Allow-Origin: *');
		echo json_encode(array('a','r','r','a','y'));
	?>

and the result is:
