Index of the node into the collection.

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";
}

?>
