Kleiner php-Parser für den OSBN-Feed
Heute habe ich mal den OSBN-Ticker bei mir eingebaut. Es scheint da schon Lösungen zu geben, aber fertige Sachen einbauen; das kann ja jeder. Daher möchte ich hier mal meine Lösung vorstellen.
Genau genommen lese ich nur die feed.rss in ein Array, durchsuche dieses anschließend nach <link> und <title>, lösche dann alle tags, und spucke das übrig gebliebene als kleine Liste aus. Das wars schon!
Mehr Daten brauche ich nicht für meinen kleinen Newsticker, was sich aber sehr einfach erweitern ließe...
Hier also der Code:
<?php
$feed = file("http://osbn.de/feed.rss");
$item = 0;
foreach ($feed as $key => $value)
{
$feed[$key] = trim($value);
$feed[$key] = html_entity_decode($feed[$key]);
if (strcmp($feed[$key],"<item>") == 0) $item++;
if ($item == 0) { unset($feed[$key]); continue; }
if ($item > 0 and $item < 9)
{
if (strncmp($feed[$key],"<link>",6) == 0 or strncmp($feed[$key],"<title>",7) == 0)
{
if (strncmp($feed[$key],"<link>",6) == 0) $descr = "link";
if (strncmp($feed[$key],"<title>",7) == 0) $descr = "title";
$tags = array("<link>", "</link>", "<title>", "</title>", "<![CDATA[", "]]>");
$data[$item][$descr] = str_replace($tags, "", $feed[$key]);
}
else { unset($feed[$key]); continue; }
}
}
unset($feed);
echo "<ul>\n";
foreach ($data as $item => $value)
{
echo "<li><a href=\"{$data[$item][link]}\" target=\"_blank\">{$data[$item][title]}</a></li>\n";
}
echo "</ul>\n";
?>Zu sehen ist das ganze dann auf meiner Startseite.
Über Verbesserungsvorschläge würde ich mich natürlich sehr freuen!
