[PHP MYSQL page requests]

Thank you for ur quick response ;)

and what about this:

<?php
//call query to add 1 to some field
//call query to substract 1 to same field
?>

User 1 requests
User 2 requests

can this happen:
u1 add
u2 add
u1 sub
u2sub

or

u1 add
u2 add
u2sub
u1 sub

this can cause inconsistance if you are not using increment or decrement but getting values, changing them and then putting them
so are those queries in 1 php page 1 thing? cause i'm still not getting that part :)

thanks!

I can't seem to find any good documented stuff about this:

When a user calls a php page, and another user calls the same
can this result in database inconsistency?

which part of query's are executed atomically:
none?
just 1 query?
1 php page?

please help me on this one?

thanks!!!
