Przykład #1 Styl obiektowy
<?php
/* Open a connection */
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
$query = "SELECT name, zip FROM hotel.city ORDER BY name";
if ($stmt = $maxdb->prepare($query)) {
/* execute query */
$stmt->execute();
/* bind result variables */
$stmt->bind_result($name, $code);
/* store result */
$stmt->store_result();
/* seek to row no. 5 */
$stmt->data_seek(5);
/* fetch values */
$stmt->fetch();
printf ("City: %s Zip: %s\n", $name, $code);
/* close statement */
$stmt->close();
}
/* close connection */
$maxdb->close();
?>
