Hi,

I have 5 textfields for user input in a form namely:

username1, username2, username3, username4 and username5

I would like to know how should I write my php code such that I will be able to check if there is any duplicates between the 5 textfields during POST?

I can only think of comparing (username1 !== username2) and so on, but I think there should be simpler way to do it right? How should I be able to do it?

Thank you very much.
