hi guys, i've had this problem for a while now

anyhow i've this is my code

 

user.php

class user

{

var name = "";

function user($n)

{

$this->name = $n;

}

 

function getName()

{

return $this->name;

}

 

util.php

include('user.php');

 

 

page1.php

include('util.php');

$user = new user("ivanh");

 

page2.php

include('util.php');

print $user->getName();

 

in page2.php i get this error:

Fatal error: Call to a member function getName() on a non-object in page2

 

please let me know if you need anything else required to help me

You never instantiate $user in page2.php (or any of it's includes)

ahhh,

i just added

 

$user = new user('ivanh');

 

into util.php so that everypage that includes util.php has this object. however, im still getting the same error.

 

im also wondering, if i do this. does this mean im making new objects or its the same one?

If you do what?

Each time you run a script, it starts from scratch. No variables that have been created in previous runs are being carried over.

This might be a good time for some web server 101 -

 

Web servers are stateless. They don't know or care what happened before or what will happen next. When any http/https request has been serviced, all resources used on the page that was requested are destroyed. The only information that ties any page request to any other page request is what the browser supplies when it makes the http/https request to the server.

 

You would need to create an instance of your class in a session variable if you wanted it to persist between any separate http/https page requests.
