Example

Пример 1. Object oriented style

Пример 2. Procedural style
<?php /* Open a connection */ $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()){ printf("Connect failed: %s\n", maxdb_connect_error()); exit(); } $query = "SELECT zip, name FROM hotel.city ORDER BY name"; if ($stmt = maxdb_prepare($link, $query)){ /* execute query */ maxdb_stmt_execute($stmt); /* store result */ maxdb_stmt_store_result($stmt); printf("Number of rows: %d.\n", maxdb_stmt_num_rows($stmt)); /* close statement */ maxdb_stmt_close($stmt); } /* close connection */ maxdb_close($link); ?>

The above examples would produce the following output:
Number of rows: 25.
