        $name = "a,b,c";
        $body = "acght";
        $nameArr = explode(',', $name);
        $res = [];
        foreach($nameArr as $value) {
            if (strpos($body, $value) !== false) {
                array_push($res, $value);
            }
        }
        $res = implode(',', $res);
        echo $res;
