SimpleXMLElement::current

(PHP 8)

SimpleXMLElement::currentReturns the current element

说明

public SimpleXMLElement::current(): SimpleXMLElement
警告

Prior to PHP 8.0, SimpleXMLElement::current() was only declared on the subclass SimpleXMLIterator.

This method returns the current element as a SimpleXMLElement object.

参数

此函数没有参数。

返回值

Returns the current element as a SimpleXMLElement object.

错误/异常

Throws an Error on failure.

更新日志

版本 说明
8.1.0 An Error is now thrown if SimpleXMLElement::current() is called on an invalid iterator. Previously, null was returned.

示例

示例 #1 Return the current element

<?php
$xmlElement
= new SimpleXMLElement('<books><book>PHP basics</book><book>XML basics</book></books>');

$xmlElement->rewind(); // rewind to first element, otherwise current() won't work
var_dump($xmlElement->current());
?>

以上示例会输出:

object(SimpleXMLElement)#2 (1) {
  [0]=>
  string(10) "PHP basics"
}
