Hello,

I have a school assignment where you are supposed to create functions that will return values to a premade driver-class called "StudentRegister.php". We are not supposed to change any values in the driver-class (picture number three), only in the function.

I've been trying to create a a function that will return single students for almost three days now, but it still won't work. Does anyone know what I'm doing wrong? Could anyone explain how the driver class communicate with my function? I don't even quite understand what I'm supposed to return..

I really appreciate your help! :D

If you want to return a value from a function, you need to use the return keyword.

With your function, you are preparing the SQL statement, but not fetching the results. So have a look at how to do this and as hyper points out, these values then need to be returned from your function.
