Is there something in PHP5 which can generate the RSS feed?
You don't need an extension to help you generate an XML feed. You
dimply output XML data instead of HTML and send an appropriate content
type header, eg:
header('Content-Type: text/xml');
You actually mean application/xml not text/xml
actually..
header("Content-type: application/rss+xml; charset=iso-8859-1")
or
header("Content-type: application/rss+xml; charset=utf-8")
And its alot better to use DOMDocument in PHP5 for XML Creation rather
than hardcode everything.
agreed in principle; and I can't belive i'm saying this.. but with the
case of a single rss feed in a single format then a tiny inline script
which echo's out is far far lighter on the server and will do the trick;
it's one of those set-up and leave scripts so DOMDocument may be
overkill in this situation.
here's an example / test code:
<?php
$rss_item_template = ' <item>
<title>RSS_TITLE</title>
<link>RSS_LINK</link>
<pubDate>RSS_DATE</pubDate>
<dc:creator>mediatakeout</dc:creator>
<category><![CDATA[news]]></category>
<guid isPermaLink="false">RSS_LINK</guid>
<description><![CDATA[RSS_DESCRIPTION]]></description>
<content:encoded><![CDATA[RSS_DESCRIPTION]]></content:encoded>
</item>
';
$rss_items = '';
$align = 'right';
if( $raw_items = $db->select("SELECT * FROM `news` LIMIT 0,20") ) {
foreach($raw_items as $index => $item ) {
$title = stripJunkSimple(stripslashes(htmlentities($item['title'])));
$link = "http://domain.com/";. $item['id']; //edit
$date = date( 'r', $item['posting_date'] ); //edit
$plain = str_replace("\n",'<br />',stripslashes($item['body']));
$in = array('RSS_TITLE','RSS_LINK','RSS_DATE','RSS_DESCRIPTION');
$out = array( $title, $link, $date, $plain );
$rss_simple_item = str_replace( $in , $out , $rss_item_template );
$rss_items .= $rss_simple_item;
}
}
$rss_template = '<?xml version="1.0" encoding="iso-8859-1"?>
<rss version="2.0"
