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"
}
