/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}

/* determine number of fields in result set */
$field_cnt = $result->field_count;
printf("Result set has %d fields.
", $field_cnt);
/* close result set */
$result->close();
}

Example #2
Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
if ($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.
", $field_cnt);
/* close result set */
maxdb_free_result($result);
