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();
}

$query "SELECT name, cno from hotel.customer ORDER BY cno";

if (
$result $maxdb->query($query)) {

   
/* Get field information for 2nd column */
   
$result->field_seek(1);
   
$finfo $result->fetch_field();

   
printf("Name:     %s\n"$finfo->name);
   
printf("Table:    %s\n"$finfo->table);
   
printf("max. Len: %d\n"$finfo->max_length);
   
printf("Flags:    %d\n"$finfo->flags);
   
printf("Type 0000BB">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();
}

$query "SELECT name, cno from hotel.customer ORDER BY cno";

if (
$result maxdb_query($link$query)) {

   
/* Get field information for 2nd column */
   
maxdb_field_seek($result1);
   
$finfo maxdb_fetch_field($result);

   
printf("Name:     %s\n"$finfo->name);
   
printf("Table:    %s\n"$finfo->table);
   
printf("max. Len: %d\n"$finfo->max_length);
   
printf("Flags:    %d\n"$finfo->flags);
   
printf($link);
?>

The above example will output something similar to:

Name:     NAME
Table:
max. Len: 10
Flags:    -1
Type:     2
