mysql 乱码的问题
网上查了一些资料,好像在我这里没有作用。
我现在mysql默认的是latin1
我创建了一个数据库 utf-general-ci,表和字段也是这个utf-general-ci,通过mysql命令查询:
show variables like 'collation_%';
-----------------------------------
collation_connection->latin1_swedish_ci
collation_database ->utf8_general_ci
collation_server ->latin1_swedish_ci
show variables like 'character_%';
-----------------------------------
character_set_client ->latin1
character_set_connection->latin1
character_set_database->utf8
character_set_filesystem ->binary
character_set_results ->latin1
character_set_sever ->latin1
character_set_system ->utf8
.php 都是utf-8编码,我在网站上直接读写中文正常,都正常。
但实际在mysql里存的是乱码,我现在mysql命令里查询也是乱码。
现在可不可以把数据库在mysql里能正常存中文?
我现在想直接mysql命令行里查询,也能显示中文,该怎么做?
------解决方案--------------------
所以地方的编码保持一致
页面、数据库、表、程序源文件。。。。
------解决方案--------------------
你在mysql控制台里输入set names gbk
然后查询就是正常的了(windows) 如果是linux就set names utf-8
------解决方案--------------------
你试下将character_set_results设为utf8,终端输入:set character_set_results=utf8
因为我对比了我的跟你show variables like 'character_%';,刚才也测试了下,将我的character_set_results改为latin1,就出现乱码。
------解决方案--------------------
你的mysql客户端要用gbk,这个在mysql的配置文件中可以改,服务器端为Utf-8,客户端用gbk
------解决方案--------------------
估计是写入的时候不对吧。
不要操心mysql的内部处理,在任何mysql连接中都先set names 客户端字符集。
如果网站是utf8,那连接后第一件事先set names utf8。
如果字符集是互相兼容的,表里面保存的数据会被正确查出来并转成你的字符集。
------解决方案--------------------
你插入数据库的时候就已经是乱了吧.修改数据库编码后重新导入数据。话说我以前也用过一段时间你说的编码好像跟utf-8还没出现啥异像
------解决方案--------------------

这是正常的,需要的也是这用的效果
但实际在mysql里存的是乱码,我现在mysql命令里查询也是乱码。
你是指在 mysql 控制台中查询吗?
那至少需要你的控制台环境是支持 utf-8 编码的
你在 gbk 环境中去看 utf-8 编码的内容,当然是乱码的
现在可不可以把数据库在mysql里能正常存中文?
我现在想直接mysql命令行里查询,也能显示中文,该怎么做?
要想不乱码,就需要使用与操作环境一直的语言编码
不要在数据库有内容的情况下修改 my.ini ,这样只会造成更大的混乱
------解决方案--------------------
如果不行的话建议重装一次,在装的时候注意选择编码的类型

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

MySQL and phpMyAdmin are powerful database management tools. 1) MySQL is used to create databases and tables, and to execute DML and SQL queries. 2) phpMyAdmin provides an intuitive interface for database management, table structure management, data operations and user permission management.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

I encountered a tricky problem when developing a small application: the need to quickly integrate a lightweight database operation library. After trying multiple libraries, I found that they either have too much functionality or are not very compatible. Eventually, I found minii/db, a simplified version based on Yii2 that solved my problem perfectly.

Article summary: This article provides detailed step-by-step instructions to guide readers on how to easily install the Laravel framework. Laravel is a powerful PHP framework that speeds up the development process of web applications. This tutorial covers the installation process from system requirements to configuring databases and setting up routing. By following these steps, readers can quickly and efficiently lay a solid foundation for their Laravel project.

When developing an e-commerce website using Thelia, I encountered a tricky problem: MySQL mode is not set properly, causing some features to not function properly. After some exploration, I found a module called TheliaMySQLModesChecker, which is able to automatically fix the MySQL pattern required by Thelia, completely solving my troubles.

In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.

The main difference between MySQL and MariaDB is performance, functionality and license: 1. MySQL is developed by Oracle, and MariaDB is its fork. 2. MariaDB may perform better in high load environments. 3.MariaDB provides more storage engines and functions. 4.MySQL adopts a dual license, and MariaDB is completely open source. The existing infrastructure, performance requirements, functional requirements and license costs should be taken into account when choosing.
