Here is what I have come up with, and it appears to work for returning one record, however if there is more than one record (wp_hud_display.id) in the database it breaks the XML, would "foreach" work in the while loop? and how would I add it to my code?
<?php // create a dom document with encoding utf8 $domtree = new DOMDocument('1.0', 'UTF-8'); //database configuration $config['mysql_host'] = "localhost"; $config['mysql_user'] = "root"; $config['mysql_pass'] = ""; $config['db_name'] = "tasmanhud"; //connect to host mysql_connect($config['mysql_host'],$config['mysql_user'],$config['mysql_pass']); //select database @mysql_select_db($config['db_name']) or die( "Unable to select database");
