I have a text file that looks like this

username|password|email (format)

eg.

joe479|mypass|[e-mail]
shawn56|s56W|[e-mail]

I want to be able to check for duplicate username and email's against a new registration input.

So that if the same email and/or username is found the new user will get an error saying the username is already taken or you can only have one account per email address

Can someone give me the code to do this. I tried exploding the file but I get errors.

Have you tried making both the username and email adress unique indexes on the table?

That way, you simply won't be able to insert duplicates.

Cheers,

Jack
