## Example

Példa 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(); } $query = "SELECT zip, name FROM hotel.city ORDER by name"; if ($stmt = $maxdb->prepare($query)) { /* execute statement */ $stmt->execute(); /* bind result variables */ $stmt->bind_result($name, $code); /* fetch values */ while ($stmt->fetch()) { printf ("%s (%s)\n", $name, $code); } /* close statement */ $stmt->close(); } /* close connection */ $maxdb->close(); ?>`

Példa 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(); } $query = "SELECT zip, name FROM hotel.city ORDER by name"; if ($stmt = maxdb_prepare($link, $query)) { /* execute statement */ maxdb_stmt_execute($stmt); /* bind result variables */ maxdb_stmt_bind_result($stmt, $name, $code); /* fetch values */ while (maxdb_stmt_fetch($stmt)) { printf ("%s (%s)\n", $name, $code); } /* close statement */ maxdb_stmt_close($stmt); } /* close connection */ maxdb_close($link); ?>`
