Description

<?php
declare(strict_types=1);

function test(int $a) {
    echo $a;
}

test('aaa');
test('111');
test(111);

demo/test.php:8 PhanTypeMismatchArgument Argument 1 (a) is 'aaa' but \test() takes int defined at demo/test.php:4

buttest('111') is Fatal error, when i run code.(because declare(strict_types=1))
PHP Fatal error: Uncaught TypeError: Argument 1 passed to test() must be of the type integer, string given, called

Research direction

Start by running the PHP reproducer with strict_types enabled and scalar_implicit_cast true, then trace the argument-type diagnostic logic. Compare the analyzer's result for 'aaa', '111', and 111 with PHP's runtime behavior. Done means the diagnostic consistently accounts for the strict_types condition without regressing other argument checks.
