You can insert into different tables like this:
EDIT (new code):
<?php
// Make a MySQL Connection
mysql_connect("localhost", "root", "root") or die(mysql_error());
mysql_select_db("double") or die(mysql_error());
// Insert a row of information into the table "example"
mysql_query("INSERT INTO example
(name, age) VALUES('Timmy Mellowman', '23' ) ")
or die(mysql_error());
// Insert a row of information into the table "example"
mysql_query("INSERT INTO example1
(name, age) VALUES('Timmy Mellowman', '23' ) ")
or die(mysql_error());
?>
Hope this answers you question because toy cant have double destination (i think) but this inserts into two different MySQL tables...
Good luck
