- 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.

snippet
<?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("sonoo",28);
$person->setAge(1);
echo "You are ".$person->display()." years old";
?>Output:
