I'm thinking about constructors usually like this:
They are functions that are invoked statically (using the `new` keyword)
on the class before the object is created, and they execute on instance
level, after the object is created.
They are called as static methods, and they are very similar to static
factory methods, and for better or worse, static methods are supported
in interfaces.
They're really more instance methods (they need an instance to exist for
them to act on, hence $this). The "new" operator creates the instance
and then the __construct method is called on that new instance.
One consequence of this is that the __construct method can be called
_after_ instantiation (because in the normal course of things it _is_):
class Foo
{
public function __construct(public int $v=0)
{
echo "Constructed {$this->v}!";
}
}
$t = Foo::__construct(5);
$u = new Foo(17);
$u->__construct(42);
