## Example

Przykład 1. Object oriented style

`<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
if ($result = $maxdb->query("SELECT * FROM hotel.city ORDER BY zip")) {
/* determine number of fields in result set */
$field_cnt = $result->field_count;
printf("Result set has %d fields.\n", $field_cnt);
/* close result set */
$result->close();
}
/* close connection */
$maxdb->close();
?>`

Przykład 2. Procedural style

`<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
if ($result = maxdb_query($link, "SELECT * FROM hotel.city ORDER BY zip")) {
/* determine number of fields in result set */
$field_cnt = maxdb_num_fields($result);
printf("Result set has %d fields.\n", $field_cnt);
/* close result set */
maxdb_free_result($result);
}
/* close connection */
maxdb_close($link);
?>`

The above examples would produce the following output:

    Result set has 3 fields.
