I try this feature in a simple project which just has these file at the porject root path:

Test1.php :

<?php
namespace ttt;
class Test1
{
    public function t1(int $a, string $b)
    {
        return $a + $b;
    }
}

Test2.php :

<?php
namespace ttt;
class Test2
{
    public static function realt2(int $h1, int $h2)
    {
        return $h1 + $h2;
    }
}

Test.php :

<?php

use ttt\Test2;

Test2::t2()->t1(1, '2');

Test2::realt2(3, 4);

.phpstorm.meta.php

<?php
namespace PHPSTORM_META {

    override(\ttt\Test2::t2(), map([
        '' => \ttt\Test1::class
    ]));
}

I excpet the .phpstorm.meta.php will work and the Test2::t2()->t1(1, '2'); in the Test.php should show me the function t1() refer to the function Test1::t1(). However, my expected results did not appear. (I have tried to reload vscode)

in_vscode

In order to verify whether my coding was wrong, I opened this project in phpstorm and saw the result I expected.

in_phpstorm

So, does this prove that the plugin does not have the effective .phpstorm.meta.php feature? Or did I use it wrongly?
