Properties Through Constructor Parameters in OOP in PHP

Variables passed through constructor parameters can be written to object properties:

<?php
	class User {
		public $name;
		public $surn;
		
		public function __construct($name, $surn) {
			$this->name = $name;
			$this->surn = $surn;
		}
	}
?>

Thus, the passed values will become available in all methods of the class. As an example, let's use the passed values in some method:

<?php
	class User {
		public $name;
		public $surn;
		
		public function __construct($name, $surn) {
			$this->name = $name;
			$this->surn = $surn;
		}
		
		public function show() {
			return $this->name . ' ' . $this->surn;
		}
	}
?>

Let's check how this works. Let's create a new object, passing the user's name and surname as parameters to it:

<?php
	$user = new User('john', 'smit');
?>

Now let's call our method:

<?php
	echo $user->show();
?>

Pass to the constructor of the class Employee the name and salary of the employee and write them to the corresponding properties.

Create a method that will display the employee's name.

Create a method that will display the employee's salary.

Create a method that will increase the employee's salary by 10%.
