Thanks for helping!
Now it works:
<?php
$con = mysql_connect("localhost","Benutzer","Passwort");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db("beta", $con);
$query = "SELECT COUNT(*) FROM Tabelle";
$result = mysql_query($query) or die(mysql_error());
list($row) = mysql_fetch_array($result);
$query2 = "SELECT SUM(Spalte) FROM Tabelle";
$result2 = mysql_query($query2) or die(mysql_error());
list($row2) = mysql_fetch_array($result2);
?>
