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.

范例

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();
}
?>

以上例程的输出类似于：

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