Store some data

//#get some object
$user=new userObject(); //#general object
$dao=new userDao(); //#DB object
//#put into collection
$colletionInstance=new MySimpleCollection();
$colletionInstance->addObject(1,$user);
$colletionInstance->addObject(2,$dao->dbObjInstance);
$colletionInstance->addObject(3,$_SESSION["URL_FROM"]);
$colletionInstance->addObject(4,serialize("daniel"));
$colletionInstance->addObject(5,unserialize(serialize("daniel")));
$colletionInstance->addObject(6,array(0=>"string",1=>array("name"=>"daniel"),"last name"=>"zhou"));
$colletionInstance->addObject(7,array(0=>"daniel"));
$colletionInstance->addObject(8,0.2356);
$colletionInstance->addObject(9,"daniel");
//#have a look
$colletionInstance->printCollection();
$iterater=$colletionInstance->getIterator();
while ($iterater->valid()) {
echo $iterater->current()."<br>";
echo $iterater->key()."<BR>";
$iterater->next();
}

then take a look
