PHP不乱码,数据库后台乱码
数据库乱码 数据库 PHP 乱码
PHP增加、修改、查询都不乱码,如图1,MySQL数据库后端显示乱码,如图2,
什么原因呢?

是用什么软件查看到乱码的
大神们,求解啊
是用什么软件查看到乱码的
Toad For MySQL
PS:到处来cvs文件也是乱码的,中文啊。。。。
你的数据库字段的连接校对是默认的 latin1 的
你存入的数据是 utf-8 的
你没有对 mysql 声明需要的字符集,所以 mysql 依然 latin1 取出数据。对于你来说就是 utf-8 了
但是 mysql 管理工具是要声明所需字符集的,于是被当做 latin1 的 utf8 转换成 utf8 时就出现了乱码现象

PS:
页面编码使用UTF-8
数据库表编码使用UTF-8

校对码是:utf8_general_ci
这就对了,如果是 latin1 的应该是插不进去 utf-8 数据的。刚才我回复时还在想,你是怎么把数据插进去的
但是这并不影响我给出的解释,只是环节有所提前而已
mysql 默认的字符集是 latin1,一般也很少有人在安装 mysql 时改变默认字符集(多数人都不知道在哪里修改)的
所以只要使用了非默认字符集操作 mysql 都必须在操作前执行 set names 字符集代码
对于 utf-8 就是 set names utf8
把以下代码用 utf-8 编码保存,然后运行一下
<?phpheader('Content-type: text/html;charset=utf-8');echo iconv('latin1', 'utf-8', '供应商-西施');
<?phpheader('Content-type: text/html;charset=utf-8');echo iconv('latin1', 'utf-8', iconv('gbk', 'utf-8', '供应商-西施'));
保证3点一致就不会乱码了:
1、数据库和数据表编码
2、页面内部编码
3、文件的编码

有点理解不了,还是不知道问题出在哪了?数据库编码应该是UTP8, :“show variables like 'character_set_database';”---》返回UTF8@~~~~~~~~~~~
关键是 character_set_server 的值
出了乱码就去找编码吧
关键是 character_set_server 的值
应用时发布在购买的虚拟主机上的,如何查看 character_set_server的值啊?
关键是 character_set_server 的值
多谢指点
show variables like 'character_set_server'
show variables like 'character_set_server'
结果是UTF-8
有点不合情理了,最后一招
select BINARY supplier_ from tbl_name where id_=17
echo base64_encode('取出的数据');
贴出结果

select BINARY supplier_ from tbl_name where id_=17
echo base64_encode('取出的数据');
贴出结果
结果如下图(该结果为数据库客户端的结果,PHP页面数据显示正常):
PS:本帖主题内容中的2张图 --》图1 为PHP页面,显示正常;图2 为数据库客户端,显示乱码,到处cvs也是乱码
你给贴图有什么用?
我要你用程序取出那个乱码的内容,并贴出其 base64 编码的值
这样才好帮你分析
再说你贴出乱码的同时也应该贴出不乱时的内容

理解了,如下图,谢谢老大
再说你贴出乱码的同时也应该贴出不乱时的内容
不乱码内容:
使用BINARY 后的乱码内容:
我要你像这样的结果
echo base64_encode($t);//w6fCscK7w6fCm8Kuw6XCm8Kb
$t 是按 BINARY(二进制)方式读出的乱码字段的内容
按图形对比(#7 的方法)你那个仍然是被当做 latin1 处理的 utf-8
这些数据是你在修改字符集之前插入的吧?

不是的哦。。 字符集没有改过,供应商说不能改,应该是插入前没有设置数据库编码为UTF8.

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 and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

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.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

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.
