A destructor is called when the object is destructed or the script is stopped or exited
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:
<?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:
<?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");
?>
Tip: As constructors and destructors helps reducing the amount of code, they are very useful!
