What is the point of the php extends in relation to classes?

[timtamboy63]

I just don't get it. Why create one class, eg

class user{
function login(){
//login stuff
}
} 

then use the extends keyword like so

class admin extends user{
function admin(){
//admin stuff
}
} 

Why not just put it in one big class and only call the admin function for when they are needed?
