serialize() and Objects

[Anon]

I have a number of classes which I instantiate and then serialize like this in one file and post out along with some form data.

$tempA = new ClassA();
$tempB = new ClassB();
$tempC = new ClassC();
// Set some variables etc
if (something)
{
$data = urlencode(serialize($tempA));
}
elseif (somethingelse)
{
$data = urlencode(serialize($temp😎);
}
else
{
$data = urlencode(serialize($tempC));
}

Later on (in a second file), I retrieve this information like this:

$getdata = unserialize(urldecode($data));

Clear? I'm not sure if I'm getting this across correctly...

Right then, how can I tell which CLASS it was from the unserialized information? Was it ClassA, ClassB or ClassC ?

Thanks in advance

I don't know if php have support some other function to deal with your trouble. But I have another stupid but easy way to get it.
Because php have not enough var check fucntion ,so if you to check isset($classA->flag) or you can set a flag to distinct the three class on the other hand. So is my idea.
I am from China. And I am looking forward to know deeply in PHP programming. If you have other good idea to work it out, pls tell me and TIA.

Make yor objects of the following form:

class ObjectExample {

var classname = "ObjectExample";

.... other code ....

}

Then when you serialize the data, you have a member variable that you can use to know which classType the objct belongs to.

Hope this helps.

Don't you just hate it when the answer is so completely obvious...

Thanks for that Greg!
