PHP classes - extending the constructor function
Hi
I have a php class called user. The constructor function takes variables and assign them.
I created this as a generic class and wish to use it to keep track of my students. Can I extend it to a new class called Students and extend the constructor function of the base class to now include a new variable called student_number?
Here is the current class:

Thank you all for the responses. I will only be able to look at it again this weekend as this is just a hobby.

To clear up the question I had.
If a base/parent class constructor function accepts arguments x and y for example
base class
constructor function(x,y){
assign x to class variable
assign y to class variable
}
and I now extend the class but want to add new variable z to the constructor function:
child class extends base class
constructor function(x,y, z){
assign x to class variable
assign y to class variable
assign z to class variable
}
do I write the whole constructor function from scratch again like above for the new extended class, in which case what is the point of extending if I have to rewrite the whole thing or is there a sneaky way to just add z as well to the original function?
