Possibly bug or incorrect code?

Remove the semicolon from "foreach($query as $result);" and try. Also, you forgot to add ending double quote in the query.

$query = $this->db->query("SELECT FROM `news` WHERE `active`=1");

foreach($query as $result) {

echo "<tr>";
echo "<td>$result->id</td>";
echo "<td>$result->msg</td>";
echo "<td>$result->from</td>";
echo "</tr>";
}
