    SimpleXMLElement::current — Returns 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"
}
