求助关于记住的cookie记数问题
setcookie("cookie_name", "abcd", time()+24*3600);

如果有设置这样子的cookie,用户只要在24小时同台电脑无需登录就可以直接登录了,但是呢,我想如果用户关闭浏览器后,重新打开浏览器想让他有个登录次数,不知道如何实现,当然如果他24小时关闭浏览器100次再打开算100个登录,我们知道如果用户自行登录可以直接update一次,但是这们子用户不登录,能否通过cookie或者其他解决,谢谢。
------解决方案--------------------
你检查cookie值就是了,存在就+1。
------解决方案--------------------
可以配合session实现

先判断session是否存在,否则读cookie,然后将cookie赋值给session。
每一次cookie赋值给session,就相当于用户login一次,cookie+1;

判断代码如下:

<?php<br />ob_start();<br />session_start();<br /><br />$login_maxtime = 5; // 用cookie 登入最大次数<br /><br />$session_login = isset($_SESSION['is_login'])? 1 : 0; // 获取session<br /><br />if(!$session_login){ // session 不存在<br /><br />    $is_login = isset($_COOKIE['is_login'])? $_COOKIE['is_login'] : 0; // 获取cookie<br /><br />    if($is_login && $is_login<$login_maxtime){  // cookie存在且,使用cookie赋值给session次数小于设定值<br />        setcookie('is_login', $is_login+1, time()+24*3600);<br />        $_SESSION['is_login'] = 1;<br />        echo 'cur login time:'.$is_login.'<br>';<br />    }else{ // 没有cookie或超过次数<br />        setcookie('is_login');<br />        $is_login = 0;<br />    }<br /><br />}else{ // session 存在<br />    $is_login = 1;<br />}<br /><br />if($is_login==0){<br />    echo 'go to login';<br />}else{<br />    echo 'logined';<br />}<br /><br />?>


模拟登入,写session,cookies
<br /><?php<br />ob_start();<br />session_start();<br />$_SESSION['is_login'] = 1;<br />setcookie('is_login', 1, time()+24*3600);<br />echo 'login success';<br />?><br />

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists

SecLists

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
