For me,
register_globals = on;

$_SESSION['foo'] = 'xxx';

...Then form operations that post few data including
$_POST['foo']='yyy'

...Now the value of $_SESSION['foo'] is set to 'yyy'

My server's PHP version is 4.3.0...The above bug is really a big problem for me...I've developed a part of the module for our big project...I've developed with the idea of register_globals=off, but other people develped with the idea of register_globals=on...And in the server, they've put it with register_globals=on... and I've started experiencing the above problem...

It worked fine on my local system (PHP4.2.3) with register_globals=off.
As, the module is related to login & session, it is a very big problem for me. Any workaround?
