SplObjectStorage::current — Returns the current storage entry
Returns the current storage entry.
此函数没有参数。
The object at the current iterator position if it exists, or null otherwise.
Example #1 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"
