You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'desc, owner, burl) VALUES ('1', '2', '3', '4', '5')' at line 1
mysql_query("INSERT INTO servers (ip, name, desc, owner, burl) VALUES ('1', '2', '3', '4', '5')") or die(mysql_error());
