Your problem description

__construct() and __destruct() are always considered to be public by PH7 Engine and this is wrong behaviour. There should be no exception in the matter of how access modifiers are working.

    <?php
            class Test {
                    private function __construct() {
                            echo "I live, again!\n";
                            self::__toString();
                    }
                    private function __destruct() {
                            echo "DONE\n";
                    }
                    private function __toString() {
                            echo "STRING\n";
                    }
            }
            Test::__destruct();

    ?>

Above example shows that when calling private __toString method from constructor it is working, but call from outside class is omitted, as expected. Anyway constructor is still called, despite it is private.

Expected results

// No output at all

Current results

I live, again!

STRING
