Just a little quirk I've come accross and I think I must be missing something so would like some clarification to further my understanding of what's going on with my code.

I post a form via jQuery AJAX, the form is processed by PHP and in the PHP I have the line

return $status;

$status is an array containing several values i.e $status['username'] = 'admin'

The AJAX datatype is set to 'JSON' but I am not using echo json_encode($status); in my PHP but everything is still working and my $status array is processed by jQuery upon AJAX success. Why is this? I thought json_encode would be required but it seems it isn't.

Such a mystery. Not encoded array and without echo, are you sure everything works? – vikingmaster Feb 17 '13 at 17:43
    
Yea it definitely works, I can get any of the values in $status to pop up in an alert message in jQuery. – David Healey Feb 17 '13 at 17:48
    
Without the context 'where' the output is actually echoed/output this will remain a mystery and we can only guess – thaJeztah Feb 17 '13 at 17:55
    
always use json_encode when trying to parse it with javascript – self Feb 17 '13 at 17:55
    
It would also help if you show us the array and function used to return $status – self Feb 17 '13 at 17:56

json_encode use but out of this function that you see the 

  return $status;

on it for understand it you can see developer tools in browser then find ajax request, see content response . for find json_encode search for location of calling this function.

Apologies I had made a daft mistake, my function was indeed returning $status, but it was returning it to another function which performed the json_encode. Mystery solved :) Thanks.
