    A friendship is essentially a mutual relationship between two people. In database terms it's a many-to-many relationship between two users.

    So what you need is a linking table that holds references to two users by ID.

    Example

    Users table

    ID    Username
    1     Bob
    2     Jim
    3     Alice
    

    Friends table

    user1    user2
    1        2
    2        3
    

    This would make Bob friends Jim and Jim friends with Alice.
