<?php
$s 
= new SplObjectStorage();

$o1 = new StdClass;
$o2 = new StdClass;

$s->attach($o1"d1");
$s->attach($o2"d2");

$s->rewind();
while(
$s->valid()) {
    
$index  $s->key();
    
$object $s->current(); // similar to current($s)
    
$data   $s->getInfo();

    
var_dump($object);

$s->next();
}

object(stdClass)#2 (0) {
}
string(2) "d1"
object(stdClass)#3 (0) {
}
string(2) "d2"
