今天第一次去面试,有好多题目都答不上来,请大神指教
第一次去面试,发现有很多跟课本不一样.
3.简单介绍一下hibernate ？
8.能熟悉Ｊａｍｅｓ服务器的配置吧？还有ｄｏｃｓ命令记得多少？（项目）
11.之前做java开发，怎么转成ＰＨＰ开发了？
14.InnoDB和MyIsAm有什么区别？
15.用ＥＬ表达式写url的路径。
这几道题,有些连名字都不认识,感觉考的挺广的,求大神指教
------解决思路----------------------
InnoDB和MyIsAm有什么区别？
InnoDB 支持事务，MyIsAm 不支持
InnoDB 慢，MyIsAm 快
InnoDB 不能直接拷贝，MyIsAm 可以直接拷贝
------解决思路----------------------
InnoDB支持行级锁，在高并发写的情况下比MyIsAm有优势
InnoDB的count()每次都要遍历
话说这看着不像php面试
------解决思路----------------------
要学会利用搜索引擎来学习！这些题也不难，baidu、Google随便一搜，就能搜出很多答案。

------解决思路----------------------
echo 12 ^ 9; // 输出为 5
echo 12^10;// 6
echo 12^12;// 0
先转2进制，在进行异或运算。
异或运算，位相同＝0 位不同＝1
例如12的二进制是
1100
9的二进制是
101
那么12 ^ 9 等于，按位异或
1100
0101
得出
1001
1001的十进制＝9
What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AMReasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.
How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AMMethods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.
What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AMMultiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.
How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AMConfiguring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.
What are the advantages of using a database to store sessions?Apr 24, 2025 am 12:16 AMThe main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.
How do you implement custom session handling in PHP?Apr 24, 2025 am 12:16 AMImplementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.
What is a session ID?Apr 24, 2025 am 12:13 AMSessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.
How do you handle sessions in a stateless environment (e.g., API)?Apr 24, 2025 am 12:12 AMManaging sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.

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),
