THECODEPROGRAM

Let's get started.

In PHP, creating classes are very easy like other programming languages which use classes like Java, C#...

Below code block you can see how to create a PHP class:

class Aircraft{
     //Properties of the class
     private $brand= "";
     private $model = "";
     private $year = 0;

     //Constructor of the class
     public Aircrat($brand, $model, $year){
          $this->brand = $brand;
          $this->model = $model;
          $this->year = $year;
    }

     //Getters and Setters of the properties of the class
     function getBrand(){ return $this->brand; }
     function setBrand($brand){  $this->brand = $brand; }

     function getModel(){ return $this->model ; }
     function setModel($model ){  $this->model = $model ; }

     function getYear(){ return $this->year ; }
     function setYear($year ){  $this->year = $year ; }

}

As you can see above we have created a class with its properties, constructor, getters and setters within it. Is it really easy isn't it ? :)
Let's use it below...

//First initialize the class with constructor
$ac = new Aircraft("Boeing", "777-200", 1994);

//Print its properties with getter methods
echo "Brand of aircraft : " . $ac->$brand . "\n";
echo "Model of aircraft : " . $ac->$model . "\n";
echo "Year of aircraft : " . $ac->$year . "\n";

Output of above code block will be:

Brand of aircraft : Boeing
Model of aircraft : 777-200
Year of aircraft : 1994

Now use defined above classes' setter methods below:

//Set the properties with through setter methods
$ac->setBrand("Airbus");
$ac->setModel("A320-213");
$ac->setYear("1987");

//Print its properties with getter methods again
echo "Brand of aircraft : " . $ac->$brand . "\n";
echo "Model of aircraft : " . $ac->$model . "\n";
echo "Year of aircraft : " . $ac->$year . "\n";

And below you will see the out put of above code block:

Brand of aircraft : Airbus
Model of aircraft : A320-213
Year of aircraft : 1987

That is all in this article.

Now you care good to use classes in your PHP project.
