Passing Object via link

Anon

I've read up on passing classes in this newsgroup but I don't really want to register it in a session. I was wondering if there was a way to pass it via an object. I tried last night with the following two pages (without success).

Is registering an object in a session really the only way to do it?

Thanks,
KABOOM!

Messing around with classes: 
<?PHP
class teams
{
// Properties
var $firstbase;
var $secondbase;

// Methods
function setFirstBase($name)
	{ $this->firstbase = $name; }

function setSecondBase($name)
	{ $this->secondbase = $name; }

function getFirstBase()
	{ return $this->firstbase; }

function getSecondBase()
	{ return $this->secondbase; }

}

$yankees = new teams();
$mariners = new teams();

$yankees->setFirstBase("Giambi");
$yankees->setSecondBase("Soriano");
$mariners->setFirstBase("Olerud");
$mariners->setSecondBase("Boone");

print "<table border=1>
<tr>
<td>Dude</td>
</tr>
</table> ";

print "<a href=\"ObjectCheck.php?teamobj=$yankees\">New York Yankees</a> 
<a href=\"ObjectCheck.php?teamobj=$mariners\">Seattle Mariners</a>";
?>

You can't pass an object reference that way. "$yankees" is a pointer to a memory space that is gone when your script ends, so you can't pass it to another script and expect the data to be there. If you want to do it that way, you have to pass all of the data in the object.

I have never tried this, but you could:

$teamData = serialize($yankees);
print "<a href=\"ObjectCheck.php?teamobj=\"" . urlencode($yankees) . "\">New York Yankees</a>;

And then on the other end:

$yankees = unserialize($teamobj);

But there are limits to the length of a GET string that web servers will parse or that browsers will send. So this would olny work if the object was small.
