store values in a class?

harmor

How do I store a value into a class and display the value on another page?

Would this be possible to do at all?

Sure, just set the class as a session and it will appear on all pages.

So, if my class was '$photo_class' then I would set a session called 'session_register("photo_class")'.

Now when I set a variable in the class, i.e. $photo_class->photo_id, I can show this anywhere on my site.

How would I set it up?
I am new to OOP and I can't seem to find a simple tutorial on storing values.

page1.php

<?php

  session_start();

  class foo
  {

private $bar;

public function setbar($val) {
  $this->bar = $val;
}

public function getbar() {
  echo "bar has the value of ".$this->bar;
}

  }

  $foo = new foo();
  $foo->setbar("hello");
  $_SESSION['foo'] = $foo;

?>
<a href="page2.php">page2</a>

page2.php

<?php

  session_start();
  $foo = $_SESSION['foo'];
  $foo->getbar();

?>

ps: this is php5 but should give you the idea. also, take note that [man]session_register/man has long been depricated.

Thank you,

I had to change a few things because I was recieving an error

 class foo
  {

var $bar;

function setbar($val) {
  $this->bar = $val;
}

function getbar() {
  echo "bar has the value of ".$this->bar;
}

  }

Just another point; you will need to have the definition of class foo on the second page as well, otherwise the second page won't know what sort of object $foo is. Best approach is to have the class definition in a separate file that you include on each page that uses the class.

Well I did it like he wrote it but on page2.php I put require "class.php";and it works.
