When you say overloading, do you mean PHP overloading, or true overloading?

[roopurt18]

AFAIK, in PHP 5 and less you can't overload a function in the true OOP sense.  You can provide optional parameters or shove a bunch of configuration parameters into a single array parameter though.

 

Perhaps you can in PHP6 but I'm uninformed about that.

Seems like a strange design this.

Wouldnt you be better splitting the staff and students into polymorphic classes defined by abstraction or an interface?

[rhodesa]

yeah, by the looks of it, it seems like a base 'person' class (or abstract class) would be best, then extend that to add the needed functionality that is specific to staff and student.
