Is it possible to forbid creating an object in the constructor of this object (php)?

Question

PHP

It's a stupid question, but still. Is it possible to forbid creating an object in the constructor of this object (php)? That is, how to ban? Whether in sense the object can destroy itself in the constructor.

Answer 1

It is generally impossible to forbid creating an instance of a class (if the class is not abstract), you can prohibit creating an instance from the outside by making the constructor private (private), but you can still create it in the class itself. Of course, you can throw an exception, but I did not check what will be the result of new.

Answer 2

question. Why do this?

Answer 3

Very similar to the singleton question .

Answer 4

php.net/manual/en/closure.construct.php

Answer 5

what? prohibit creating an instance? private function __construct()
or inside __construct to prohibit creation of other objects? then no
or I don’t understand a damn thing
