初3数学 =》 数据结构与算法
这个过程中 需要哪几本数学书 来过渡!
或者说 只要先学哪些内容就可以过渡过来,比较快速,能举例具体哪些章节 最好啦!
(还是说所有"高中-大学"的数学都要学,花费很多时间)。
回复讨论(解决方案)
大学里面的《高等数学》,把它学好吧
算法估计是离不开高数了,可怜我该看高数的时光都看了高树了……唉,菩提参天大树啊,阿弥陀佛
另外一条路(方向不同,说的不是殊途同归)就是讲解集合概念的 ==>(也少不了高数) 《线性代数》+《概率论》 ==> 《离散数学》

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 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),
