Example

例 1086. 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();
}

$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();
?>

例 1087. 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();
}

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);
?>

The above examples would produce the following output:
