范例

Example#1 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();
?>

Example#2 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:

Warning: maxdb_query(): -8004 POS(62) Constant must be compatible with column type and length <...>
Number of warning: 0
