Bug report

PHPStan complains this function returns an array (not necessarily a list):

/**
 * @return list<string>
 */
function get_cv_files(): array
{
    $pdo = new PDO("");
    $stmt = $pdo->prepare('SELECT `file` FROM `commonvoice`');
    $stmt->execute();

    return $stmt->fetchAll(PDO::FETCH_COLUMN);
}

Code snippet that reproduces the problem

https://phpstan.org/r/860e662d-152e-4631-813f-dea50f9dbb6e

Expected output

fetchAll(PDO::FETCH_COLUMN) will always return a list.

Did PHPStan help you today? Did it make you happy in any way?
