范例

Example#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();
}

/* 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));

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

The above examples would produce the following output: 

Protocol version: 10
