Question

Can you do this in PHP? I’ve heard conflicting opinions:

Something like:

Class bar {
   function a_function () { echo "hi!"; }
}

Class foo {
   public $bar;
   function __construct() {
       $this->bar = new bar();
   }
}
$x = new foo();
$x->bar->a_function();

Will this echo “hi!” or not?

It’s perfectly fine, and I’m not sure why anyone would tell you that you shouldn’t be doing it and/or that it can’t be done.

Your example won’t work because you’re assigning new Bar() to a variable and not a property, though.

$this->bar = new Bar();
