7.4 PHP Destructor

• A destructor is called when the object is destructed or the script is stopped or exited.
• If you create a __destruct() function, PHP will automatically call this function at the end of the script.
• Notice that the destruct function starts with two underscores (__)!
• The example below has a __construct() function that is automatically called when you create an object from a class, and a __destruct() function that is automatically called at the end of the script:

Example 1: PHP Destructor part 1

<?php
class Fruit {
  public $name;
  public $color;

  function __construct($name) {
    $this->name = $name;
  }
  function __destruct() {
    echo "The fruit is {$this->name}.";
  }
}

$apple = new Fruit("Apple");
?>

Another example:

Example 2: PHP Destructor part 2

<?php
class Fruit {
  public $name;
  public $color;

  function __construct($name, $color) {
    $this->name = $name;
    $this->color = $color;
  }
  function __destruct() {
    echo "The fruit is {$this->name} and the color is {$this->color}.";
  }
}

$apple = new Fruit("Apple", "red");
?>
