Just do it, it works perfectly.

Yes:
session_start();
$_SESSION['myobject'] =& $myobject;
What you need to observe is that the class MUST be declared BEFORE the
session is reloaded:
// won't work
session_start();
class A {
function A() {}
}
if (!$a) {
$a = new A();
$_SESSION['a'] =& $a;
}
Here your session is started _before_ the class gets declared. This works
for the first time, but when reloading the session object $a will be
reconstructed without the class definition readily available, so PHP will
default to a standard class. The next example will work, though:
class A {
function A() {}
}
session_start();
if (!$a) {
$a = new A();
$_SESSION['a'] =& $a;
}
As you can see the class decl is given _before_ the session is started.
