How to get list of urls with a limit of (for example) 25 urls In PHP ?

Answer 1

It can be done by using this code :

$rss = new DOMDocument();
$rss->load('http://wordpress.org/news/feed/');
$feed = array();

foreach ($rss->getElementsByTagName('item') as $node) {
    $item = array (
        'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,
    );
    array_push($feed, $item);
}

$limit = 5;

for($x=0;$x<$limit;$x++) {
    echo $link = $feed[$x]['link'];
}
