/* 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);
?>
