do you mean the code that produces the output for javascript?

$user = null;

$userData = array();

try
{

if(isset($_SESSION['name'])){
$userData['name'] = $_SESSION['name'];
}
if(isset($_SESSION['userid'])){
$userData['userid'] = $_SESSION['userid'];
}

}
catch(Exception $e)
{
logger($e->getMessage());
echo "Error : " .$e->getMessage();
}

echo $userData;

not much use, it just produces 'Array' plain text. If that's the case, do you mean i'll actually have to organise my own data into an understandable structure, and then chop it out from javascript and pass back to an array manually?

such as from php,

echo $myArrayStr = "name='mr box' | age=20 | sanity = 'not really' ";

then in javascript,

maybe some sorta split function that separates the "|" delimeter and assign them all into javascript?
