FILTER_SANITIZE Deprecated

[ShadowVoid-King]

$filterdUser = filter_var($username, FILTER_SANITIZE_STRING);
$filterdEmail = filter_var($email, FILTER_SANITIZE_EMAIL);

in php 8.1.0 i think alternative can be one of next solution so which one is best practices and why ?

$filterUser = strip_tags(filter_var(htmlspecialchars($_POST['username'], ENT_QUOTES, 'UTF-8'), FILTER_SANITIZE_FULL_SPECIAL_CHARS)); // Work Too

$filterUser = htmlspecialchars((strip_tags($_POST['username'])), ENT_QUOTES, 'UTF-8'); // Work Too
