How do I include a variable in each PHP page

[underthefake]

I want to include a variable (for example an object $user) in each PHP page.

 

Previously I declared $var in an include file then included that file in every page, however it generates an error in Zend Studio and it's also not very good programming style.

 

I want to know how I can do it any other way.  I was thinking of using constants but I don't know if constants should be used for this purpose and also I do not think constants can be defined as objects.

 

Thank you very much for your help.

using sessions and session variables you can 'carry' variable(s) to multiple pages

I have read online that large objects in the session will impact performance greatly.  My objects will be quite large so I don't think using sessions will be the best.

if you don't want to store objects in sessions, store them in a database table and store the row identifier in a session var.
