Retrieve a node specified by index in PHP

/*from w  ww. j  a v a 2 s . c om*/
<?php

$doc = new DOMDocument;
$doc->load('test.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:


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