Don't, simple as that.
Even if the student_id column is a string based column - and that's the only way you will get multiple values in there, as a comma separated string - it's a PITA to work with from that moment on.
Instead, create a separate table which links the user ID to the StudentID and store one ID value pair per row. It's a whole load easier to work with when you need to refer to the data again.
