Using __set()

Aside from method overloading, property overloading is another aspect of the PHP overloading capabilities. There are four magic methods in PHP that support the property overloading: __set(), __get(), __isset(), and __unset(). Throughout this section, we will take a closer look at the __set() method.

The __set() magic method is triggered when trying to write data to inaccessible properties. 

The method accepts two parameters, as per the following synopsis:

public void __set(string $name, mixed $value)

Whereas, the __set() method parameters have the following meaning:

• $name: This is the name of the property being interacted with
• $value: This is the value that the $name property should be set to

Let's take a look at the following object context example:

<?php

class User
{
  private $data = array();

  private $name;
  protected $age;
  public $salary;

  public function __set($name, $value)
  {
    $this->data[$name] = $value;
  }
}

$user = new User();
$user->name = 'John'...
