# DOMNodeList::item

(PHP 5, PHP 7)

DOMNodeList::item — Retrieves a node specified by index

### Descrierea

DOMNodeList::item ( int `$index` ) : DOMNode

Retrieves a node specified by `index` within the DOMNodeList object.

Sfat

If you need to know the number of nodes in the collection, use the length property of the DOMNodeList object.

### Parametri

`index`

  Index of the node into the collection.

### Valorile întoarse

The node at the `index`th position in the DOMNodeList, or `NULL` if that is not a valid index.

### Exemple

Example #1 Traversing all the entries of the table

`<?php
$doc = new DOMDocument;
$doc->load('book.xml');
$items = $doc->getElementsByTagName('entry');
for ($i = 0; $i < $items->length; $i++) {
echo $items->item($i)->nodeValue . "\n";
}
?>`

Alternatively, you can use foreach, which is a much more convenient way:

`<?php
foreach ($items as $item) {
echo $item->nodeValue . "\n";
}
?>`
