PHP中文乱码问题总结
PHP中文乱码是PHP开发中的常见问题之一。
PHP中文乱码有时发生在网页本身，有些产生在于MySQL交互的过程中，有时与操作系统有关。下面进行一番总结。
一．首先是PHP网页的编码
最好最快的解决办法就是,页面申明的编码与数据库内部编码一致,如果页面申请的页码与数据库内部编码不一致时,就设定连接编码 ,mysql_query("SET NAMES XXX "); XXX为连接编码.一定可以解决乱码的问题.
1. php文件本身的编码与网页的编码应匹配 a. 如果欲使用gb2312编码，那么php要输出头：header(“Content-Type: text/html; charset=gb2312")，静态页面添加锛
Explain how load balancing affects session management and how to address it.Apr 29, 2025 am 12:42 AMLoad balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Are there any alternatives to PHP sessions?Apr 29, 2025 am 12:36 AMAlternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching
Define the term 'session hijacking' in the context of PHP.Apr 29, 2025 am 12:33 AMSessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID.

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),
