You could, but I would advice you against to do a such thing, as you will most
likely get trouble to see from where the value comes when you are to debug
your code a long time later or it can be someone else who does the debugging.

Use a normal global value instead, like

$myvalue = "myvalue";

This don't make any sense, you assign a value to an array and then exit the
script and you loose the value at the same time.

The alternative to sessions are called cookies, but it's really not an
alternative as sessions usually are cookies.
