In this example, $psid is not being overwritten by $_SESSION['psid'].
That's why you get the 1111 twice.

According to your code, it should not happen the second time either. Is
there any chance you've got register_globals on in your php.ini file?
If so, you should turn it off immediately. It's a huge security problem
and a "feature" which will be removed in PHP 6.

But it still doesn't explain why you get two different outputs.

BTW, the output is incorrect (according to your code, it should be '111
111'). Please be careful when copying your code as minor errors can
cause large differences in the results.
