PHP CONSTRUCTOR
- A constructor allows you to initialize an object's properties upon creation of the object.
- If you create a __construct() function, PHP will automatically call this function when you create an object from a class.
- Constructors are the very basic building blocks that define the future object and its nature.
- You can say that the Constructors are the blueprints for object creation providing values for member functions and member variables.
- Constructors are special member functions for initial settings of newly created object instances from a class.
SYNTAX OF CONSTRUCTOR IN PHP :
<class-name>: :<class-name> (list-of-parameters){ // constructor definition }

return $this->name;
}
}
$apple = new Fruit ( "Apple" ) ;
