Why is this an issue?

In PHP both the way to declare a constructor and the way to make a call to a parent constructor have evolved. When declaring constructors with the __construct name, nested calls to parent constructors should also use the new __constructor name.

Noncompliant code example

class Foo extends Bar {
  function __construct() {
    parent::Bar();
  }
}

Compliant solution

class Foo extends Bar {
  function __construct() {
    parent::__construct();
  }
}
