PHP 7+ solves a problem with __invoke noted about 4 yrs ago:
<?php
class a {
function __construct() { }
function __invoke() { echo("Invoked\n"); }
}
$a = new a();
$a();
// Output: Invoked
class b {
private $x;
function __construct() {
$this->x = new a();
($this->x)(); // Works in PHP 7+
// $this->x(); // Will blow up in your face: undefined method b::x
}
}
$b = new b();
// Output: Invoked
