Thank you for the clarification. :D
So, basically, this would be better?
Code:
<?php
include("include/config.php");
$db=mysql_connect ($db_host,$db_user,$db_pass) or die ('I cannot connect to the database because: ' . mysql_error());
mysql_select_db ($db_name);
mysql_query("TRUNCATE TABLE `guest_info`");
#mysql_query("TRUNCATE TABLE `playlist`"); // uncomment if you also don't want to track peoples entire playlists.
mysql_close($db);
#print "Your guests and their play lists (if playlists has been included in the flush) have been cleared from the database.";//UNCOMMENT IF YOU RUN THIS MANUALLY
#print "
";//UNCOMMENT IF YOU RUN THIS MANUALLY
#print "Return to the main page";//UNCOMMENT IF YOU RUN THIS MANUALLY
