hello friends,
I am looking into 4 books in front of me but somehow cannot find the
following :
I have a field userid which the user fills in at registration. Before
entering the data into the database, I want to check if the userid exists in
the database.
Can someone tell me the name of the function I must use, I will look for the
rest in the php dictionary.
Thanks
Denis
