RE: [PHP] Session Variables

The session variable values get stored to the session file (or database, or wherever your configuration is set to store them) at the end of script 1. When session_start() is called in script 2, those values get restored from the session file. So, your results are expected: PHP needs to store the session values from script 1 before they can be retrieved by script 2.
