示例 #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();
}
?>
