How to return values ?

[Jmacp]

If i pass a php script a value from a webpage how can i have to return the value ?

I know how to get the incoming data using $_GET or $HTTP_POST_VARS the process or whatever bit don't know how to actually return the reuslts to the page.

Well,

If the URL is something along the lines of

http://www.example.com/file.php?id=34

Then to show the value of id you would do this.

<?
$id = $_GET['id'];
echo $id;
?>

or

<?
$id = $_REQUEST['id'];
echo $id;
?>

If it is a POST value then it is basically the same,

<?
$id = $_POST['id'];
echo $id;
?>

or

<?
$id = $_REQUEST['id'];
echo $id;
?>

I hope this helps =)
