例

<?php
$xmlIterator = new SimpleXMLIterator('<books><book>PHP basics</book><book>XML basics</book></books>');
var_dump($xmlIterator->current());

$xmlIterator->rewind(); // rewind to first element
var_dump($xmlIterator->current());
?>

以上例程會輸出：

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