I tried your example Andrei and the methods are not available, however the
properties are and retain the value of $a->b

<? // Page 1
# save session
include "foo.class.php";
session_start();
session_register("a");
$a = new foo;
$a->b = 10;
?><a href=page2.php>Page 2</a>

<? // Page 2
# restore session
include "foo.class.php";
session_start();
var_dump($a);
?><br><a href=page1.php>Page 1</a>
<? $a->p(); ?> // This prints Call to undefined function: p() in....


<? // foo.class.php
class foo {
  var $a;
  var $b;
  var $c;
  function foo() {
    echo "foo()<BR>\n";flush();
    $this->a = 1;
    $this->b = "a";
    $this->c = array("hallo");
  }
  function p() {
    echo $this->a." ".strlen($this->b)." ".count($this->c)."<BR>\n";
    $this->a++;
    $this->b.="a";
    $this->c[]="hallo";
  }
}
?>


: Yes, it is possible. Example:
:
: <?
: # save session
: include "foo.class.php";
: session_start();
: session_register("a");
: $a = new foo;
: $a->bar = 10;
: ?>
:
: <?
: # restore session
: include "foo.class.php";
: session_start();
: var_dump($a);
: ?>
:
: The second piece of code should print out your class and the methods
: should be available.
