SplObjectStorage::current — Returns the current storage entry

### 说明

public function SplObjectStorage::current(): 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.

### 更新日志

版本 | 说明
--- | ---
8.1.0 | SplObjectStorage::current() now throws an Error exception if the current position is invalid. Previously, `false` was returned instead.

### 示例

示例 #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();
    }
    ?>

以上示例的输出类似于：

    object(stdClass)#2 (0) {
    }
    string(2) "d1"
    object(stdClass)#3 (0) {
    }
    string(2) "d2"
