What is Constructors and Destructors?

CONSTRUCTOR : PHP allows developers to declare constructor methods for classes. Classes which have a constructor method call this method on each newly-created object, so it is suitable for any initialization that the object may need before it is used.

DESTRUCTORS : PHP 5 introduces a destructor concept similar to that of other object-oriented languages, such as C++. The destructor method will be called as soon as all references to a particular object are removed or when the object is explicitly destroyed or in any order in shutdown sequence.

class Base {
function __construct() {}
function __destruct() {}
}
class Object extends Base {
function __construct() {
parent::__construct();
}
function __destruct() {
parent::__destruct();
}
}
$obj = new Object();
unset($obj);
