Warning: mysql_connect(): Can't connect to MySQL server on 'explosif_dk' (111) in /customers/explosif.dk/explosif.dk/httpd.www/test/list.php on line 8

<b>Nogen der kan hjælpe???

Har brugt et eksembel fra en bog:</b>
<?php
$link_id = mysql_connect ("explosif_dk", "explosif_dk", "xxxxxx");
$result = mysql_list_dbs($link_id);
$num_rows = mysql_num_rows($result);

while($db_data = mysql_fetch_row(result)) {
            echo $db_data[0]. "<BR>";
            $result2 = mysql_list_tables($db_data[0]);
            $num_rows2 = mysql_num_rows($result2);
            while($db_data = mysql_fetch_row(result2)) echo "--" .
$table_data[0]. "<br>";
            echo "==> $num_rows2 table(s) in " . $db_data[0] . "<P>";
}
?>
