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 all columns */
   
$finfo = $result->fetch_fields();

   foreach (
$finfo as $val) {
       
printf("Name:     %s\n", $val->name);
       
printf("Table:    %s\n", $val->table);
       
printf("max. Len: %d\n", $val->max_length);
       
printf("Flags:    %d\n", $val->flags);
       
printf("Type:     %d\n\n", $val->type);
   }
   
$result->close();
}

/* 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();
}

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

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

   
/* Get field information for all columns */
   
$finfo = maxdb_fetch_fields($result);

   foreach (
$finfo as $val) {
       
printf("Name:     %s\n", $val->name);
       
printf("Table:    %s\n", $val->table);
       
printf("max. Len: %d\n", $val->max_length);
       
printf("Flags:    %d\n", $val->flags);
       
printf("Type:     %d\n\n", $val->type);
   }
   
maxdb_free_result($result);
}

/* close connection */
maxdb_close($link);
?>

The above examples would produce the following output:

Name: NAME Table: max. Len: 10 Flags: -1 Type: 2 Name: CNO Table: max. Len: 4 Flags: -1 Type: 0
