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" }
