PHP class constructor and destructor with example 2020

---

PHP out of the box provides us few magic methods. Constructor and destructor are the important magic methods. So when we create a class object (Initialize a class). It Constructor function fires automatically. Now when we delete the variable where we stored the class object refrence then destructor function fires.

Have a look on this code

class Test
{
    public $name = 'Marcus ';
    public $statement = ' Object Died';

    //Constructor method 
    public function __construct()
    {
        echo $this->displayName();
    }


    //custom method
    public function displayName()
    {
        return $this->name;
    }

    // Destructor method
    public function __destruct()
    {
        echo $this->statement;
    }
}

$test = new Test();

unset($test);

Now when we create object here

$test = new Test();

This line of code fires the construct method. After that we are using “Unset” function from PHP. to delete the “$test” variable. This is when destruct will fire.
