<?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(); ?>
