SplObjectStorage::current() 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(); } ?>
以上例程的输出类似于:
object(stdClass)#2 (0) { } string(2) "d1" object(stdClass)#3 (0) { } string(2) "d2"
