how to display only 5 records?
What i want to do is read rssfeed, so I already did it, but I display as foreach loop, so how can I only display 5 records ? now I get more than 10 records, but I only need top 5 records, Isn't anyway php, javascript or jquery make it only show 5 records?
here is my code to read the rss file:
function getrssFeed($feed_url) {
$content = file_get_contents($feed_url);
开发者_Python百科$x = new SimpleXmlElement($content);
echo "<ul>";
foreach($x->channel->item as $entry) {
echo "<li><a href = '$entry->link' title='$entry->title'><h3>" . $entry->title . "</h3></a>" . $entry->pubDate . "<br /><br />" . strip_tags($entry->description) . "</li>";
}
echo "</ul>"; }
getrssFeed("http://thestar.com.my.feedsportal.com/c/33048/f/534555/index.rss");
thank you
the easiest way would be to stop your loop after 5 iterations:
$i = 0;
foreach($x->channel->item as $entry) {
// do something
$i++;
if($i==5){
break;
}
}
another (more beautiful) way would be to use a for
-loop instead of foreach
:
for($i=0; $i<=min(5, count($x->channel->item)); $i++) {
$entry = $x->channel->item[$i];
// do something
}
EDIT :
thanks to Juhana, i changed the code to take that into account.
Try putting a counter in your foreach loop with an if statement to check when the counter is over 5. If the counter is under 5 -> display RSS post, counter++. Else -> Exit loop.
Why not use a simple for loop instead?
for($i = 0, $i <= 5, $i++) {
echo "<li><a href = '$x->channel->item[$i]->link' title='$x->channel->item[$i]->title'><h3>" . $x->channel->item[$i]->title . " </h3></a>" . $x->channel->item[$i]->pubDate . "<br /><br />" . strip_tags$x->channel->item[$i]->description) . "</li>";
}
You can use jQuery feed Plugin.
$('div.feed').Feed({
count:5;
});
<div class="feed" link="http://thestar.com.my.feedsportal.com/c/33048/f/534555/index.rss" ></div>
Feeds would be loaded to container feed.
