Hi,

I lost four hours debbuging a stupid-useless bug. I created an object Adress and then wanted to give it to another php page via header().
That's what I did : 

## file A.php ##
include (Adress.php); // contains Adress object definition
$temp = new Address();
$_SESSION["temp"] = serialize($temp);
header(Location: B.php);

## file B.php ##
$temp = unserialize($_SESSION[$temp]);
echo $temp->street; // echo nothing because file B doesn't include Address.php

Two way of finding my error a lot faster : 
- the system could have crashed when I deserialized the object because it didn'n new the object type
- the system could have crashed when I tried to use the object attribute for the same reason

Please make a decent programming language out of php, save the world.
