php session Error

hi all,

If any one knows the meaning of following error, and way to rectify plz tell...


Warning: Unknown: Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in Unknown on line 0

Oh that's pretty confusing one
Took me a hours to dig out. Even php source code were examined.

Make sure you don't have $_SESSION array key names matching global variable name.
E.g. if you have $_SESSION['cart'] variable and $cart variable in same script, one of them must be changed.
Name it $_SESSION['sess_cart'] and error will disappear.

also, variable declaration would help
