这段代码存在语法错误，无法正常执行，需要进行修正。假设修正后代码如下：

if (isset($_POST['submitT']) && $_POST['id'] != null) {
    $id = $_POST['id'];
    $query = "select username, email from member where id=$id";
    $result = execute($link, $query);
    if (mysqli_num_rows($result) >= 1) {
        while ($data = mysqli_fetch_assoc($result)) {
            $username = $data['username'];
            $email = $data['email'];
            $html .= "<p class='notice'>hello, {$username}<br />your email is: {$email}</p>";
        }
    } else {
        $html .= "<p class='notice'>False</p>";
    }
}

该代码存在SQL注入漏洞，攻击者可以在`id`参数中注入恶意SQL语句，从而导致数据库被攻击者控制，或者获取到敏感信息。建议使用参数化查询或者对输入进行过滤和校验，避免SQL注入漏洞的发生。
