Universal Objects?

[paraleadogg]

Hi,

 

I have a quick question. I am learning OO PHP and wondered if someone could help.

 

I have a class called user

 

This class contains parameters (firstname, username etc) and methods (getDetails())

 

If i create an instance of a user in my index page like this:

 

require('user_class.php');

 

$user = new user();

 

$user->getDetails;

 

echo $user->firstname;

 

This of course works fine.

 

However if i then go to a new page (example.php) and try and access the $user object i cant. I have to instantiate it again

 

$user = new user();

 

And then get details AGAIN

 

$user getDetails();

 

My question is - how can  create the object once and have it universally available throughout my site?? it seems stupid to have to create a new instance on every single page??

As long has your class definition exists before the session_start() statement, you can create or use a session variable for the instance of your class -

Hmmm ok - I didnt realise you could store an object in a session

 

But that then begs the question - what is the point of the object then??

 

Icould just set some session variables directly from the database result set no?

Object Oriented Programming is sorta like a generic skeleton for your application.

 

The benefit of storing information in a session is that you don't need a database, thus, increasing the speed of your application. In addition, you can access the information from any page, as long as you start your application with session_start().
