you are simply asking someone to do your assignment?that's not fair. we all are here to help on some clues or ideas rather than programming other's stuffs. Can you please explain what you have done and what you want?

Editors supporting php can ease to eliminate this issue. They highlight the end/start of the tag near which the mouse is placed/clicked. For instance notepad++. Why don't give a try?

why not to try all the core things with a simple mysql query on mysql console: mysql>select *from users_table where username='abcd'; if this returns non-zero entries then there is the entry for the user. mysql>select *from users_table where username="abcd" and password=md5('passwd'); if this returns non-zero rows then the provided username and pwd is eligible for login. Please let me know if need further help.

what about stored procedures? Aren't they easy to manage for atomicity?
