PHP constructors & destructors
Constrcutor:Constructor methods for classes can be declared. Classes having a constructor method can call this method on each new object.
Syntax:Void __ construct(arguments);
Example:Class base
{
Function __constrcutor()
{
Print “In base class”;
}
}
Parent constructors are not called implicitly if the child class defines a constructor. In order to run a parent constructor, a call to parent::__construct() within the child constructor is required.
Destructor:The destructor methods are called as soon as all references to a particular object are removed or when the object is explicitly destroyed.
Like constructors, parent destructors will not be called implicitly by the engine. In order to run a parent destructor, one would have to explicitly call parent::__destruct() in the destructor body.
Example:Function __destruct()
