<?php

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

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

if (
$result $maxdb->query("SELECT cno, name FROM hotel.customer ORDER BY name")) {

   
/* determine number of rows result set */
   
$row_cnt $result->num_rows;

   
printf("Result set has %d rows.\n"$row_cnt);

   
/* close result set */
   
$result->close();
}

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

Example #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 (
$result maxdb_query($link"SELECT cno, name FROM hotel.customer ORDER BY name")) {

   
/* determine number of rows result set */
   
$row_cnt maxdb_num_rows($result);

   
printf("Result set has %d rows.\n"$row_cnt);

   
/* close result set */
   
maxdb_free_result($result);
}

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