Interlink Script with phpBB

[William959]

Hello good afternoon.

I'm developing an "independent" phpBB script. In this script has a field that is Forum User, in it I want to check if there is a user registered with the data that he filled out and I want to compare the emails.

Could you tell me the name of the database and the .php files that phpBB uses? Where is the table of registered users in my forum?
