Description:
------------
Now that PHP supports named parameters, those names in the documentation must match the used in the PHP source. 

E.g. in the documentation for mysqli::__construct(), '$host' and '$dbname' are wrong.

Expected result:
----------------
From file ext/mysqli/mysqli.stub.php in the source:

public function __construct(
    ?string $hostname = null,
    ?string $username = null,
    ?string $password = null,
    ?string $database = null,
    ?int $port = null,
    ?string $socket = null
)

Actual result:
--------------
From https://www.php.net/manual/en/mysqli.construct.php :

public mysqli::__construct(
    string $host = ini_get("mysqli.default_host"),
    string $username = ini_get("mysqli.default_user"),
    string $passwd = ini_get("mysqli.default_pw"),
    string $dbname = "",
    int $port = ini_get("mysqli.default_port"),
    string $socket = ini_get("mysqli.default_socket")
)
