范例
Example #1 面向对象风格
<?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('11111',
'Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch')";
$maxdb->query($query);
printf ("Number of warning: %d\n", $maxdb->warning_count);
/* close connection */
$maxdb->close();
?>
Example #2 过程化风格
<?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 */
$query = "INSERT INTO temp.mycity (zip, name) VALUES('11111',
'Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch')";
maxdb_query($link, $query);
printf ("Number of warning: %d\n", maxdb_warning_count($link));
/* close connection */
maxdb_close($link);
?>
