This is roughly how it works:
<?php
//user.php
$user = new User();
class User {
//some stuff
}
?>
<?php
//file a.php
//NEW $user object is created
include('user.php');
//do some stuff
//$user is DESTROYED, end of script
?>
<?php
//file b.php
//NEW $user object is created
include('user.php');
//do some stuff
//$user is DESTROYED, end of script
?>
If you want to keep the first $user object and persist it across pages,
then you can many different things, but you need to put it in the
session. One example (you could also write a session class to take care
of all of your session stuff):
<?php
//user.php
class User {
//some stuff
}
?>
<?php
//file a.php
include('user.php');
session_start();
if(isset($_SESSION['user'])) {
$user = unserialize($_SESSION['user']);
} else {
$user = new User();
}
//do some stuff
//save $user to session
$_SESSION['user'] = serialize($user);
//$user is DESTROYED, end of script, but $_SESSION['user'] persists
?>
<?php
//file b.php
include('user.php');
session_start();
if(isset($_SESSION['user'])) {
$user = unserialize($_SESSION['user']);
} else {
$user = new User();
}
//do some stuff
//save $user to session
$_SESSION['user'] = serialize($user);
//$user is DESTROYED, end of script, but $_SESSION['user'] persists
?>
