# SplObjectStorage::current

(PHP 5 >= 5.1.0, PHP 7, PHP 8)

SplObjectStorage::current — Returns the current storage entry

### 说明

public 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"
