php连接SQL文件编码的问题,上次草草结贴,又出问题,求解
本人是用php做的数据库连接,存入数据的时候就出问题了,但是用php把数据的编码方式进行了修改,
===========================================
iconv("utf-8","gbk",$array[2])
===========================================
存入正确了,但是就是取出数据的时候出问题了,想着再用原来的方法换回来,但是没办法换回来了...
取中文并打印到网页的时候都变成了“??”...想来是数据编码的问题,就是不知道改怎么统一
我的PHP编码是用的utf8 数据库也是utf8,是不是和浏览器的编码也有关系?...
下面有我的错误页面。
------解决方案--------------------
mysql_query("set names utf8"); //执行查询前加上这一句
防止页面输出乱码可在php文件行首加上:header("content-type:text/html;charset=utf-8");
------解决方案--------------------
<br /> $link=@mysql_connect(HOST,USER,PASS) or die("数据库连接失败");<br /> mysql_select_db(DBNAME,$link);<br /> <br /> mysql_query('set names utf8');<br /> <br /> $sql="select * from users where username='{$username}' and state=1";<br /> $result=mysql_query($sql,$link);<br />
发送sql语句前,加上mysql_query('set names utf8');就可以解决了,前提是数据里面是中文,不能是乱码!
------解决方案--------------------
这个很你的数据库编码有问题,你进msyql数据库看看,还有就是mysql_query("set names utf8");再有就是网页的bom问题。解决不了就把截图贴出来,帮你看看

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.
