Re: [PHP-PEAR] Object persistence

Thanks Vinai,

This works!  I am not sure what I was doing wrong.  Sorry for wasting
bandwidth on this issue.

FYI, here are my 3 test scripts: a Test class (Test.inc), a page where a
Test instance is created, registered, and attributes echoed (page1.php),
and a subsequent page (page2.php) where the attributes are again echoed
(without being created and registered).

The scripts demonstrate that once you register an object to a session, on
subsequent pages you can access the scalar values, array values, and
methods associated with that object.

I am using PHP  4.0.4pl1

<?php

// Script Name: Test.inc

class Test {
  var $auth_table      = 'access_control';
  var $access_levels   = array();

  function Test () {
    $this->access_levels['student']  = 1;
    $this->access_levels['admin'] = 2;
  }

  function printAccessLevel($user_type) {
    echo $this->access_levels[$user_type];
  }
}

?>

<?php

// Script Name: page1.php

require_once "Test.inc";

session_start();
session_register('test');

$test = new Test;

echo "Access control table: $test->auth_table <BR>";

echo "Access Level for Students: ". $test->access_levels['student']
."<BR>";

echo "Print Access Level for Admin: ";
$test->printAccessLevel("admin");
echo "<BR>";

echo "<a href='page2.php'>Next Page</a>";

?>

<?php
// Script Name: page2.php

require_once "Test.inc";

session_start();

echo "Access control table: $test->auth_table <BR>";

echo "Access Level for Students: ". $test->access_levels['student']
."<BR>";

echo "Print Access Level for Admin: ";
$test->printAccessLevel("admin");
echo "<BR>";

?>
