It works for me like this:

<?php
$xml = simplexml_load_file("http://www.voetbalzone.nl/rss/rss.xml");

for ($i = 0; $i < 10; $i++)
{
    $title = $xml->channel->item[$i]->title;
}

?>

Note that you are overwriting the variable $title each time, so that you will have the title of the 10. element in it after the loop finished [I assume that is not what you want?]

To get all 'item'-Elements inside 'channel' as an Array to iterate through you can use xpath like this:

<?php
$xml = simplexml_load_file("http://www.voetbalzone.nl/rss/rss.xml");

$item_array = $xml->xpath("//rss/channel/item");

foreach($item_array as $item) {
    echo $item->title . "
";
}
?>

I would suggest to read about php's SimpleXML here: http://php.net/manual/en/book.simplexml.php
