Example

例子 1. Object oriented style

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

/* check connection */
if (maxdb_connect_errno()) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

if (!$maxdb->query("SELECT xxx FROM hotel.city")) {
   printf("Errorcode: %d\n", $maxdb->errno);
}

/* close connection */
$maxdb->close();
?>

例子 2. Procedural style

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

/* check connection */
if (maxdb_connect_errno()) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

if (!maxdb_query($link, "SELECT xxx FROM hotel.city")) {
   printf("Errorcode: %d\n", maxdb_errno($link));
}

/* close connection */
maxdb_close($link);
?>

The above examples would produce the following output:
