RSS einbinden

[Saphier]

Moin,

ich habe ein problem mit www.easyphp.org und zwar werden diese Fehlermeldungen bei mir angezeigt, wenn ich versuche einen RSS feed auf meiner Website anzuzeigen.


über dem Header

<?php
include 'include\rss.php';
include_once("include\analytics.php");

$url = 'http://rss.golem.de/rss.php?feed=RSS2.0';
?>

oder irgen ein anderer RSS-Feed


irgend wo im content

   <?php
                        
                        $rss = new RSSParser($url ,"utf-8");
                        
                        $s = count($rss->titles);
                        if($s > 8)
                            $s = 8;
                        for($x = 0;$x < $s;$x++)
                        {
                            
                            $s1 = explode("<a","".$rss->descriptions[$x]);
                            $s2 = explode("></a>",$s1[1]);
                            $s2[0] = preg_replace("/maxImageHeight=400&maxImageWidth=400/","maxImageHeight=150&maxImageWidth=150",$s2[0]);

Kann nicht sein, das würde eine andere Fehlermeldung ergeben. Der Fehler kommt aber wahrscheinlch dadurch zu Stande, dass du nicht prüfst, in wieviele Teile [man]explode[/man] die Zeichenkette zerlegt.

Dafür brauchst du kein Script aus dem Netz. Schau dir mal simplexml an, damit solltest du ohne Probleme RSS Feed parsen können.
