  • SplObjectStorage::current()

    (PHP 5 >= 5.1.0, PHP 7)

    Returns the current storage entry

    说明

    publicSplObjectStorage::current(void) : object

    Returns the current storage entry.

    参数

    此函数没有参数。

    返回值

    The object at the current iterator position.

    范例

    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"
