范例

Example #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();}?>

以上例程的输出类似于：

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