[PHP] session_start ()

[shawn]

When using session_start () over alot of pages, do i need to reregister the origional 
session? 
example:

page1:session_start();
          session_register('data');

page2:session_start();

page3:session_start();
          session_register('data');

new to sessions, (no really), so thanks for the help, ill be going through the manual 
while I wait :-)
