header("Location: index.php?g=admin")
根目录下的admin.php文件的代码是：
header("Location: index.php?g=admin");
exit;
我是新手，对这样的跳转不理解，请问这是跳转到哪里？
------解决思路----------------------
index.php
------解决思路----------------------
不是有 require("./thinkphp/setup.php"); 吗
你如何知道 thinkphp/setup.php 不处理 g=admin 这个参数呢
------解决思路----------------------
thinkphp，又是这个害人框架。
------解决思路----------------------
想知道为什么会跳转到后台的逻辑，只能一步一步的追踪代码了。既然出现了跳转的结果，说明参数g=admin一定是被处理了。可能会涉及几个文件，要有耐心。。
------解决思路----------------------
框架要统一入口，所有的请求一律落在index.php上，这样非常方便管理
但为了方便用户，放一个admin.php跳到真正的后台入口处

What is session regeneration, and how does it improve security?May 02, 2025 am 12:15 AMSession 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.
What are some performance considerations when using PHP sessions?May 02, 2025 am 12:11 AMPHP 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.

What are some best practices for securing PHP sessions?May 01, 2025 am 12:22 AMThe 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 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 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.
