SplObjectStorage::getInfo() example

<?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($object);
    var_dump($data);
    $s->next();
}
?>

The above example will output something similar to:

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