示例 #1 SplObjectStorage::next() 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)

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

int(0)
object(stdClass)#2 (0) {
}
int(1)
