<?

while($i%5==0){
echo "<table>";
for($k=0; $k<5; $k++){
$db->next_datensatz();
echo "<td>";
echo "<table width="100%" border="0" cellspacing="0" cellpadding="0">\n";
echo "<tr>\n";

printf("<td>%s</td>",@date("d.m.Y",$db->f("datum")) );
echo "</tr>\n";
echo "<tr>\n";
echo "<td><img src="grafik/spacer.gif" width="441" height="1"></td>\n";
echo "</tr>\n";
echo  "<tr>\n";
echo  "<td><span class="verdana11schwarz">\n";
printf("<strong>%s</strong>\n",nl2br($db->f("titel")) );
echo" </span></td>\n";
echo" </tr>\n";
echo" <tr>\n ";
echo" <td valign="top"><span class="verdana11schwarz">\n";
printf("%s [<a href="detail.php?nid=%d">weiter...</a>]",nl2br($db->f("short_text")),$db->f("nid") );
echo" </span></td>\n";
