我将一个数组序列化放到了MySQL里面,然后用PHP获取后,用JSON格式发送出去,接口接受此数据的时候,再将JSON转化为了数组,最后发现这个数组product_list键所对对应的序列化数组不能被反序列化,这是为什么呢?
- A数组中的 product_list是数组
- 将product_list序列化入库
- PHP 查询数据库出来,将整个大数组转换为JSON 发送给接口调用方
4.请求的接口放将JSON转换为数组,成功转换为数组后,发现数组的 product_list键,所对应
的反序列化数据转换为数组失败

可能是因为中文编码的缘故。php 反序列化的时候依赖字节长度。
不要用 php 序列化存进去了, 转成 json ,这样通用性也好很多。谁能保证,这些数据是一直被 php 读取呢?
我曾经遇到过这么个情况,同一个字符串,我在本地序列化的结果,跟在远程服务器上序列号的结果不一样。因为对我的系统不影响,所以我没有深究。但是我知道有这种现象会发生:
或许是因为php版本的问题,或许是因为php扩展的问题,更或许是因为编码等等某些原因,在不同的服务器环境中,PHP序列化的结果是不稳定不可靠的。

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.
