No to both. When I arrive at the new page, the sessions vars (as expected)
contain the values set by the previous page. $ref_page is not set. The
values are transferred to $ref_page by the function. That works as planned.
I then reset the value of the session vars, at which point, $ref_page also
gets set. From printing out the values after each line, I find this:
Let's say we've come from the page /community.php and have arrived
at /market.php. Here are the values at each stage:
$_SESSION['ref_page] = '/community.php'
$_SESSION['ref_pagequery'] = 'pagemode=index' // as an example
53. $ref_page = get_ref_page();
$ref_page['name'] = '/community.php'
$ref_page['query'] = 'pagemode=index'
$_SESSION['ref_page] = '/community.php'
$_SESSION['ref_pagequery'] = 'pagemode=index'
54. $_SESSION['ref_page'] = THIS_PAGE;
$ref_page = '/community.php' // now a scalar
$_SESSION['ref_page] = '/market.php'
register_globals is off (in php.ini and there are no .htaccess files).
