$maxdb->close();
?>

Example #2 过程化风格

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')"
