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(); } $query = "SELECT name, zip FROM hotel.city ORDER BY name"; if ($stmt = $maxdb->prepare($query)){ /* execute query */ $stmt->execute(); /* bind result variables */ $stmt->bind_result($name, $code); /* store result */ $stmt->store_result(); /* seek to row no. 5 */ $stmt->data_seek(5); /* fetch values */ $stmt->fetch(); printf ("City: %s Zip: %s\n", $name, $code); /* close statement */ $stmt->close(); } /* close connection */ $maxdb->close(); ?>

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(); } $query = "SELECT name, zip FROM hotel.city ORDER BY name"; if ($stmt = maxdb_prepare($link, $query)){ /* execute query */ maxdb_stmt_execute($stmt); /* bind result variables */ maxdb_stmt_bind_result($stmt, $name, $code); /* store result */ maxdb_stmt_store_result($stmt); /* seek to row no. 400 */ maxdb_stmt_data_seek($stmt, 5); /* fetch values */ maxdb_stmt_fetch($stmt); printf ("City: %s Zip: %s\n", $name, $code); /* close statement */ maxdb_stmt_close($stmt); } /* close connection */ maxdb_close($link); ?>

The above examples would produce the following output:
City: Dallas Zip: 75243
