Beispiel #1 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();
}
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

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