completely in PS(http_session_vars). This avoids bugs which are caused by a lack of synchronization between the two hashes. We also don't need to worry about prioritizing one of them. Add session.bug_compat_42 and session.bug_compat_warn which are enabled by default. The logic behind bug_compat_42: IF bug_compat_42 is on, and IF register_globals is off, and IF any value of $_SESSION["key"] is NULL, and IF there is a global variable $key, then $_SESSION["key"] is set to $key. The extension emits this warning once per script, unless told otherwise. "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.
