Example
Příklad 987. 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 cno, name FROM hotel.customer ORDER BY name")) {
/* determine number of rows result set */
$row_cnt = $result->num_rows;
printf("Result set has %d rows.\n", $row_cnt);
/* close result set */
$result->close();
}
/* close connection */
$maxdb->close();
?>
Příklad 988. 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 cno, name FROM hotel.customer ORDER BY name")) {
/* determine number of rows result set */
$row_cnt = maxdb_num_rows($result);
printf("Result set has %d rows.\n", $row_cnt);
/* close result set */
maxdb_free_result($result);
}
/* close connection */
maxdb_close($link);
?>
The above examples would produce the following output:
Result set has 15 rows.
