同一个mysql数据源,同一个浏览器,访问线上测试无乱码,localhost访问就有乱码,我想这是不是服务器环境的问题?
补充:中文在mysql中显示是正常的。
补充:本地和测试服务器php.ini中default_charset
都是注释掉的。
补充:my bad, 我习惯的认为应该不是mysql设置字符编码的问题(基于代码都是一样的),当我试着指定字符编码时,问题得以解决。常理说来,编码问题无非三个地方,php,mysql,浏览器设置,都统一问题一般都没有了。

按照你的说法,既然数据库是同一个,浏览器也是同一个,代码也肯定是同一个了,那么基本上问题出在php上,
1.查看你的php配置的默认编码是否是utf-8,最好拿phpinfo()看一下
<code>default_charset = "utf-8";</code>
2.查看你的数据库连接抽象层,在php与MySQL交互的地方,是否设定了编码规则,如果你用的是mysqli,最起码要这样设定一下
<code>$mysqli->set_charset("utf8")</code>
1、HTML 文档的 head 指定了与后端处理程序指定的一致的编码了没有呢?
2、查看一下数据库里的表或字段使用的编码,是否与后端程序的编码一致(不一致的话,比如 UTF-8 强行转 GBK 可能导致乱码)。

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
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),
