Hello, mailing list, I have problem with this oop code:
<?
class Person {
var $name, $address, $age;
function Person($name, $address, $age) {
$this->name = $name;
$this->address = $address;
$this->age = $age;
}
}
Class Employee extends Person {
var $position, $salary;
function Employee($name, $address, $age, $position, $salary) {
$this->Person($name, $address, $age);
$this->position = $position;
$this->salary = $salary;
}
}
Class Displayer extends Employee {
function DisplayEmployee() {
echo "Name: " . $this->name . "<br>";
echo "Address: " . $this->address . "<br>";
echo "Age: " . $this->age . "<br>";
echo "Position: " . $this->position . "<br>";
echo "Salary: " . $this->salary . "<br>";
}
}
$obj1 = new Employee("Orlando J Pozo P","Calle 75 AV 9B-10","20","Computer Engineer","$2000");
$obj2 = new Displayer;
$obj2->DisplayEmployee();
?>

Warning: Missing argument 1 for employee() in C:\htdocs\ojpp\poo\3\practica\Copy of 18.php on line 16

I don't know what happen in this code, because, the last inheritance (Displayer Class) that I made, it is inherited the properties and methods of the Employee Class, and as Employee Class is also inherited the functionality of the parent class, the Displayer Class would be inherit this functionality, too.
thanks if any could help me, regards, bye.
