that is not right and has been discussed a thousand times over.
The declare changes the rules only for function calls in the file it is
declared in.
so:
lib.php:
<?php
declare(strict_types = 1);
function foo(int $a) {
// no function call here
}
?>
The declare here does just nothing.
<?php
require "lib.php";
foo("123"); // will work
?>
<?php
declare(strict_types = 1);
require "lib.php";
foo("123"); // will give an error
?>
Very easy, explained a thousand times over. Bringing up the same false
arguments up again and again does really not help the discussion.
