Title Body

I'm still kind of new to PHP OO programming techniques and I have a very simple broad question, is it generally bad practice to instantiate a class in a class then pass that instance to another class? What I want is to be able to create an instance of a specific class I know I will always need through each user request. Class two is more than anything just a helper class, ideally in my application it would be a "loader" that loads the views. First class which calls the other two classes: require 'classTwo.php'; require 'classThree.php'; class first { public $classTwo, $classThree; public function __construct() { $this -> classTwo = new classTwo; $this -> classThree = new classThree; $this -> classThree -> displayNum( $this -> classTwo ); } } Second class which is the helper class: class classTwo { public function returnVal() { return 123; } } Third class is the action class where actual work and final display would happen: class classThree { public function displayNum( $instance ) { echo $instance -> returnVal(); } } Overall I just want to know if this is bad practice because I never seen it done before. Thanks in advance!
