## Example

Beispiel 1. Procedural style

`<?php maxdb_debug("trace packet 200"); $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (!$link) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); } /* close connection */ maxdb_close($link); ?>`

The above example produces no output.
