Bug description: Session variably overwritten with global variable
Description:
------------
When a class is instantiated globally, and assigned to a variable name
which is the same as a session variable, then the session variable get
overwritten with the class.
This may happen with non-class variables, but I am not sure.
Reproduce code:
---------------
changing $entrain to anything else (i.e. $entra) fixes the problem.
<?php
session_start();
$entrain = new entrainRuntime();
var_dump($_SESSION);
class entrainRuntime
{
function entrainRuntime ()
{
$_SESSION['entrain'] = array();
}
}
?>
Expected result:
----------------
array(1) {"entrain" => array(0) {}}
this happens the first time, expected
Actual result:
--------------
On subsequent refreshes:
array(1) {"entrain" => &bject(entrainruntime)(0) {}}
