PHP - The __destruct() Function
The PHP __destruct() function is a special method within a class that is automatically called when an object is destroyed or when the script finishes execution.
The PHP __destruct() function is the opposite of the PHP __construct() function.
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
html
<?php
class Fruit {
public $name;
public $color;
function __construct($name, $color) {
$this->name = $name;
$this->color = $color;
}
function __destruct() {
echo "Name: "
. $this->name . ". Color: " . $this->color .".<br>";
}
}
$apple = new Fruit('Apple', 'Red');
$banana = new Fruit('Banana',
'Yellow');
?>
Tip: As constructors and destructors helps reducing the amount of code, they are very useful!
