How can i limit the number of articles (retrieved from an RSS) shown in php per page ? (Eg 10 articles per page)
Question:
Tag: javascript,php,html,dom,rss
Here is the code : I retrieve data from an RSS and i show them in a php page. These data are items (Articles) which contains title, date, description ... Now i want to show just 10 articles per page. Please how can i do that. Thank you
<?php
$fichier = 'http://korben.info/feed';
$dom = new DOMDocument();
$slashNS = "http://purl.org/rss/1.0/modules/slash/";
if (!$dom->load($fichier)) {
die('Impossible to load the XML');
}
$itemList = $dom->getElementsByTagName('item');
foreach ($itemList as $item) {
$titre = $item->getElementsByTagName('title');
$date = $item->getElementsByTagName('pubDate');
if ($titre->length > 0) {
echo $titre->item(0)->nodeValue;
} else {
echo '(sans titre)';
}
echo date (" d/m/Y - H:i", strtotime($date->item(0)->nodeValue))."\t";
echo '<br />' . 'Nmber of comments : ' . $item->getElementsByTagNameNS($slashNS, 'comments')->item(0)->nodeValue;
echo '<br />'."\n";
$desc = $item->getElementsByTagName('description');
if ($desc->length > 0) {
echo ' '.$desc->item(0)->nodeValue."\n";
}
$lien = $item->getElementsByTagName('link');
if ($lien->length >0) {
echo ' <a href="'.$lien->item(0)->nodeValue.'">Article complet</a>';
}
echo '<br/>'."\n".'<br/>'."\n".'<br/>'."\n";
}
?>
Answer:
One thing you can do is break the foreach loop when a counter reaches 10.
$i = 0;
foreach ($itemList as $item) {
$i++;
// ...
if($i>9){ break; }
}
Or, restructure into a for() loop, and surround ALL the code inside with an if() statement similar to above.
