Example#1 Object oriented style

/* 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 Procedural style

`<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
/* print protocol version */
printf("Protocol version: %d\n", maxdb_get_proto_info($link));
