Example #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();
}
$query = "SELECT zip, name FROM hotel.city ORDER BY name";
if ($stmt = $maxdb->prepare($query)) {
/* execute query */
$stmt->execute();
/* store result */
$stmt->store_result();
printf("Number of rows: %d.\n", $stmt->num_rows);
/* close statement */
$stmt->close();
}
/* close connection */
$maxdb->close();
?>
Example #2 Procedural style
<?php
/* Open a connection */
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
$query = "SELECT zip, name FROM hotel.city ORDER BY name";
if ($stmt = maxdb_prepare($link, $query)) {
/* execute query */
maxdb_stmt_execute($stmt);
/* store result */
maxdb_stmt_store_result($stmt);
printf("Number of rows: %d.\n", maxdb_stmt_num_rows($stmt));
/* close statement */
maxdb_stmt_close($stmt);
}
/* close connection */
maxdb_close($link);
?>
