我在php.ini中更改了
<code>session.save_handler = files -> session.save_handler = redis session.save_path = "/tmp" -> session.save_path = "tcp://127.0.0.1:6379"</code>
更改之后访问了一下,就突然多出这么多字段,但是都没有值。
如下:
这东西到底是什么鬼。
不好意思没有讲清楚。这些东西是在没有访问的情况下保存的,我完全没有访问服务器,又多了三个。
顺便提问一下,这样设置的session最后可以自动释放吗?过期时间到了之后会自动删除吗?

session_id
你再看看phpini里面session.autostart配置的是啥。
如果这个配置成1了,你不调用session_start系统会自动帮你调用会生成session ID,你不存东西,自然就是空的
可以查看 session 的配置 (http://php.net/manual/zh/session.configuration.php) 了解详细的情况
session 默认是有概率触发 gc 的,也就是垃圾回收
session 如果已经过期了,但是没有触发 gc, 那么还会存在着,等到下次 gc 的时候删去
至于你说的,没有访问服务器多了几条记录,你在仔细看看,确实发生了访问
php应该已经触发了,在mac中好像有其他东西在触发。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
