Example

Пример 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();

}

$maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city");

/* a remarkable city in Wales */

$query = "INSERT INTO temp.mycity (zip, name) VALUES('',

'Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch')";

$maxdb->query($query);

printf ("Number of warning: %d\n", $maxdb->warning_count);

/* close connection */

$maxdb->close();

?>

Пример 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();

}

maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city");

/* a remarkable long city name in Wales */

$query = "INSERT INTO temp.mycity (zip, name) VALUES('',

'Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch')";

maxdb_query($link, $query);

printf ("Number of warning: %d\n", maxdb_warning_count($link));

/* close connection */

maxdb_close($link);

?>

The above examples would produce the following output:
