OOP in PHP

Class constructor


You can initialize the data members of an object when it is created by using the constructor method. The name of constructor is the same as the name of the class.

Example:
<?php

class Employee
{
//data member
private $emp_id;
private $emp_name;
private $emp_sex;
private $emp_salary;

//constructor with parameters
Function Employee($id,$name,$sex,$salary){
$this->emp_id=$id;
$this->emp_name=$name;
$this->emp_sex=$sex;
$this->emp_salary=$salary;
}

//method members
function setName($name){
$this->emp_name=$name;
}
function getName(){
return $this->emp_name;

}
}

$emp=new Employee("e001","Dara Chan","Male",1500);//create object and initialize data members
echo "ID:".$emp->emp_id."<br>";
echo "Name:".$emp->getName();//access method member



?>
