hello... here's the code
what i wanted to know is how do I list only the 5 first items from the xml? the foreach is taking all items from the xml code.

<?php
require_once "XML/RSS.php";

$rss =& new XML_RSS("sample.xml");
$rss->parse();

echo " <ul>\n";

foreach ($rss->getItems() as $item) {

echo "<li><a href=\"" . $item['link'] . "\">" . $item['title'] .
"</a></li>\n";

}

echo "</ul>\n";
?>

PHP Code:


			
    $i = 0;

    foreach ($rss->getItems() as $item) {

        echo "<li><a href=\"" . $item['link'] . "\">" . $item['title'] . "</a></li>\n";
        
        ++$i;
        
        if($i === 5) break;

    }

Alternatively you could only feed the first 5 items into the foreach.

PHP Code:


			
<?php

require_once "XML/RSS.php";



$rss =& new XML_RSS("sample.xml");

$rss->parse();



echo " <ul>\n";



// Use only the first 5 items

$items = array_slice($rss->getItems(), 0, 5);



foreach ($items as $item) {



echo "<li><a href=\"" . $item['link'] . "\">" . $item['title'] .

"</a></li>\n";



}



echo "</ul>\n";

?>

I am sure if you look in the documentation or even the class itself they establish what it returns.

Why not use a FOR loop?

Yes, $rss->getItems() returns an array.
