thanx a lot, i've solved the problem.

can php run two queries at the same time?
for example, i insert the record to the table B, then delete from the table A.

why don't you just run 2 queries?

The time difference between Query 1 & Query 2 is a fraction of a second... (depending on size of query of course)

I think it's about MySQL query, is'n it ?

Yes right, more than just one,two, or more mysql query could be execute in just one single webpage.
... event query in the same table

for ex :
mysql_query("INSERT INTO table1 (name,email) VALUES ('ridwank','my@mail.com')");

mysql_query("INSERT INTO table1 (name,email) VALUES ('jerry','jerry@mail.com')");

mysql_query("UPDATE table1 SET email='your@mail.com' WHERE name='ridwank'");

mysql_query("DELETE FROM table1 WHERE name='jerry'");
