Example

Пример 1. Object oriented style
<?php /* Open a connection */ $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()){ printf("Connect failed: %s\n", maxdb_connect_error()); exit(); } $query = "SELECT name, state FROM hotel.city ORDER BY name"; if ($result = $maxdb->query($query)){ /* seek to row no. 10 */ $result->data_seek(10); /* fetch row */ $row = $result->fetch_row(); printf ("City: %s State: %s\n", $row[0], $row[1]); /* free result set*/ $result->close(); } /* close connection */ $maxdb->close(); ?>

Пример 2. Procedural style
<?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (!$link){ printf("Connect failed: %s\n", maxdb_connect_error()); exit(); } $query = "SELECT name, state FROM hotel.city ORDER BY name"; if ($result = maxdb_query($link, $query)){ /* seek to row no. 400 */ maxdb_data_seek($result, 10); /* fetch row */ $row = maxdb_fetch_row($result); printf ("City: %s State: %s\n", $row[0], $row[1]); /* free result set*/ maxdb_free_result($result); } /* close connection */ maxdb_close($link); ?>

The above examples would produce the following output:
City: Irvine State: CA
