Пример 1. Object oriented style

<?

$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

/*check connection*/

if (maxdb_connect_errno()) {

printf("Connect failed: %s\n", maxdb_connect_error());

exit();

}

/*create temp table*/

$maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city");

$query = "INSERT INTO temp.mycity SELECT * FROM hotel.city WHERE state LIKE ?";

/*prepare statement*/

if ($stmt = $maxdb->prepare($query)) {

/*Bind variable for placeholder*/

$code = 'N%';

$stmt->bind_param("s", $code);

/*execute statement*/

$stmt->execute();

printf("rows inserted: %d\n", $stmt->affected_rows);

/*close statement*/

$stmt->close();

}

/*close connection*/

$maxdb->close();

?>

Пример 2. Procedural style

<?

$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

/*check connection*/

if (maxdb_connect_errno()) {

printf("Connect failed: %s\n", maxdb_connect_error());

exit();

}

/*create temp table*/

maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city");

$query = "INSERT INTO temp.mycity SELECT * FROM hotel.city WHERE state LIKE ?";

/*prepare statement*/

if ($stmt = maxdb_prepare($link, $query)) {

/*Bind variable for placeholder*/

$code = 'N%';

maxdb_stmt_bind_param($stmt, "s", $code);

/*execute statement*/

maxdb_stmt_execute($stmt);

printf("rows inserted: %d\n", maxdb_stmt_affected_rows($stmt));

/*close statement*/

maxdb_stmt_close($stmt);

}

/*close connection*/

maxdb_close($link);

?>

- The above examples would produce the following output: 
rows inserted: 4
