Example #1 面向对象风格

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

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

/* print protocol version */
printf("Protocol version: %d\n"$maxdb->protocol_version);

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

Example #2 过程化风格

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

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