$req = cubrid_prepare($conn, "INSERT INTO publishers VALUES(?, ?, ?, ?, ?)");

$id_list = array("P01", "P02", "P03", "P04");
$name_list = array("Abatis Publishers", "Core Dump Books", "Schadenfreude Press", "Tenterhooks Press");

$country_list = array("USA", "USA", "Germany", "USA");

for ($i = 0, $size = count($id_list); $i < $size; $i++) {
    cubrid_bind($req, 1, $id_list[$i]);
    cubrid_bind($req, 2, $name_list[$i]);
    cubrid_bind($req, 3, $city_list[$i]);
    cubrid_bind($req, 4, $state_list[$i]);

    if (!($ret = cubrid_execute($req))) {
        break;
    }
}

if (!$ret) {
    cubrid_rollback($conn);
} else {
    cubrid_commit($conn);

    $req = cubrid_execute($conn, "SELECT * FROM publishers");
    while ($result = cubrid_fetch_assoc($req)) {
        printf("%-3s %-20s %-15s %-3s %-15s\n",
