Get current user data

Question

I do work on filter posts by current user, but in my dropdown list, i can get only all users list, but I need to see only the current user

function getСurrentUserForFilter(){
    $res = '';
    $user_query = new WP_User_Query(array('number'=>999));
    $users = $user_query->get_results();
    foreach($users as $user){
        echo'<option value="'.$user->ID.'">'.$user->user_email.'</option>';
    }
    return $res;
}

what am I doing wrong?

If you just want to write a single <option> for the current user, you can get the user object from wp_get_current_user() - you don't need a WP_User_Query at all:

function getСurrentUserForFilter() {
    if ( is_user_logged_in() ) {
        $user = wp_get_current_user();
        echo '<option value="'.$user->ID.'">'.esc_html($user->user_email).'</option>';
    }
}
