SimpleXMLElement::rewind — Rewind to the first element
Prior to PHP 8.0, SimpleXMLElement::rewind() was only declared on the subclass SimpleXMLIterator.
This method rewinds the SimpleXMLElement to the first element.
Nota: As of PHP 8.4.0, calling get methods (such as SimpleXMLElement::asXML() or SimpleXMLElement::getName()) or casting a SimpleXMLElement to a string no longer implicitly rewinds the iterator. Where required, the iterator must be rewound explicitly by calling this method.
Questa funzione non contiene parametri.
Nessun valore viene restituito.
Example #1 Rewind to the first element
<?php
$xmlElement = new SimpleXMLElement('<books><book>PHP Basics</book><book>XML Basics</book></books>');
$xmlElement->rewind();
var_dump($xmlElement->current());
?>Il precedente esempio visualizzerà:
object(SimpleXMLElement)#2 (1) {
[0]=>
string(10) "PHP Basics"
}
