Encapsulation in PHP

Encapsulation is a concept where we encapsulate all the data and member functions together to form an object.
Wrapping up data member and method together into a single unit is called Encapsulation.
Encapsulation also allows a class to change its internal implementation without hurting the overall functioning of the system.
Binding the data with the code that manipulates it.
It keeps the data and the code safe from external interference.

Example 1

  <?php  class person  {  public $name;  public $age;  function __construct($n, $a)  {  $this->name=$n;  $this->age=$a;  }  public function setAge($ag)   {     $this->ag=$ag;     }     public function display()     {     echo  “welcome “.$this->name.”<br/>”;     return $this->age-$this->ag;     }     }     $person=new person(“tutor”,28);     $person->setAge(1);     echo “You are “.$person->display().” years old”;     ?>
