You've got to be careful about your language when dealing with php and
other such languages, when considering web pages.
You have said: "declaring your session variable on page1.php".
Now do you mean "on the web page that is displaed as a result of
executing page1.php", or "in the script file page1.php".
This is important because there does not need to be a one-to-one
relationship between a .php file and a web page.
One php file may display zero, one or more than one web page.
Alternatively a web page may be made up of output from more than one
php script file.
