这是部分数据库中取出来的数据:user|a:11:{s:3:"uid";s:1:"8";s:5:"email"
我想将它转换成数组,如何实现?

这个问题 ... 怎么说呢 ... 满满都是槽点反而给人一种无从下手的感觉啊 ...
首先 ... 你无法把原生的 数组
以 任何方式 存入 数据库
...
不管 BLOB
也好 TEXT
也罢 ... 都不行 ...
想要保存 ... 必须把数组转换成字符串的形式 ... 这个过程就是所谓的 序列化
...
序列化不拘泥于算法 ... 你可以用任何一种可以将数组和字符串互相转换的方法 ...
顶楼的数据 ... 就是一个经过了这样处理之后的数组 ...
有句老话叫解铃还需系铃人 ...
想要拿到原来的数据 ... 要去看这个数组是被怎样的算法处理的 ...
虽然我不太明白这样存储的意义是什么 ... 在我看来这种方式很莫名 ...
但我觉得实现了这个存储的人 ... 一定实现了数据的读取 ...
Save 与 Load 在正常情况下总是成对儿存在 ... 去读读代码一定会有帮助 ...
哈罗我是懒蛋分割线当然你如果你连读代码的心思都没有 ... 那我也可以猜一个实现给你 ...
我只能从你顶楼的只言片语里面猜 ... 不一定准确 ...
用于读取还可以尝试 ... 不建议用于修改数据库里面的原始内容 ...
<?php /* this is the blob data read from database ... */ $string = 'PUT_YOUR_DATA_HERE'; /* i guess string always start with name| ... */ $parts = explode( '|', $string, 2 ); /* now we will trying to restore two parts ... */ $$parts[0] = unserialize( $parts[1] ); /* i registered a new variable which name as same as 1st part ... */ print_r( $user );
最后的变量名字就是你的原始数据里面第一个 | 之前的内容 ...
例子里是 $user 因为你顶楼的提供的数据以 user 开头 ...
我不确定你的完整数据里是否只有一个数组 ... 或者有很多 ...
如果有很多还涉及到在数组里面的 | 转义的问题 ... 就会比较麻烦 ...
没看全内容 ... 按照简单的办法猜测就是这样了 ... 希望能帮助你 ...
用到的是 php 的内置序列化算法 serialize() ... 看一看总没坏处 ...
嘛 ... 不知不觉写了好多 ... 就当睡觉之前活动一下了 ... 健康好睡眠!

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.

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),
