utf8转成gbk

使用set names 字符集
Character_set_client
character_set_result
character_set_connection 这三项在cmd黑窗口中设置为set names gbk;时那数据文件层与系统管理层是utf8 在cmd窗口查询的时候数据从文件中取出经过数据管理层然后到达character_set_result这里在这一过程中应该会有编码转换问题不要从 utf8转成gbk不？那如果这一转换应该会有乱码才对

回复讨论(解决方案)

需要，而且你的文件编码也应该是gbk

如果你什么cmd直接连接mysql client操作的话，不需要，mysql自动转换的

如果你实在cmd下执行php的话，输出时根据php文件编码决定的。

从数据库到php是一次IO，从php echo到cmd也是一次IO，要注意两次IO前后的编码变化

你说cmd，应该是windows吧，windows的cmd默认是跟随系统编码的，如简体中文的windows其cmd默认是cp936(相当于gbk)编码，此编码可以通过注册表做永久改变，或使用"chcp xxx"命令临时改变，其中xxx是编码号，936相当于gbk，65001相当于utf-8

在cmd最开始输入chcp 65001回车，cmd的窗口就变成相当于utf-8编码输出了

注：cpxxx是微软定的编码，和对应的通用编码有很轻微的不同，一般使用时不涉及这些差异的内容，所以上面所说都是“相当于”

楼上的学习了默默收藏

只要你的数据字段的连接校对是中文系列的（gbk、big5、utf8、ucs-2、utf-16....)
那么你在使用时只需 set names 字符集，以后就可按你需要的字符集进行操作
编码转换的工作由 mysql 替你完成

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

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.

How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP vs. Python: Use Cases and ApplicationsApr 17, 2025 am 12:23 AM

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Apr 17, 2025 am 12:22 AM

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP: An Introduction to the Server-Side Scripting LanguageApr 16, 2025 am 12:18 AM

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP and the Web: Exploring its Long-Term ImpactApr 16, 2025 am 12:17 AM

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.
