You are only updating data, RDBMS (I assume MySQL) doesn't cache UPDATE queries. If you still want to use bind variables (security? performance?), you will have to use prepared statements:

$db = Zend_Db_Table_Abstract::getDefaultAdapter();
$stmt = $db->prepare("UPDATE table SET key = :key, value = :value");

foreach ($data as $key=>$value) {
    $stmt->bindParam('key', $key);
    $stmt->bindParam('value', $value);
    $stmt->execute();
}

But unless you are having millions of UPDATE queries in a batch I don't think you should bother with this. Just use the $table->update($data, $where);
