Answer 1

have a look at mysql_insert_id()

here the documentation: http://in.php.net/manual/en/function.mysql-insert-id.php

Answer 2

fairly simple if you use stored procedures:

call insert_user_and_profile('f00','http://www.f00.com');

full script:

drop table if exists users;
create table users
(
user_id int unsigned not null auto_increment primary key,
username varchar(32) unique not null
)
engine=innodb;

drop table if exists user_profile;
create table user_profile
(
profile_id int unsigned not null auto_increment primary key,
user_id int unsigned not null,
homepage varchar(255) not null,
key (user_id)
)
engine=innodb;

drop procedure if exists insert_user_and_profile;

delimiter #

create procedure insert_user_and_profile
(
in p_username varchar(32),
in p_homepage varchar(255)
)
begin
declare v_user_id int unsigned default 0;

insert into users (username) values (p_username);
set v_user_id = last_insert_id(); -- save the newly created user_id

insert into user_profile (user_id, homepage) values (v_user_id, p_homepage);

end#

delimiter ;

call insert_user_and_profile('f00','http://www.f00.com');

select * from users;
select * from user_profile;
