HomeBackend DevelopmentPHP TutorialWamp-PHPMyAdmin 用户问题

MySQL 数据库 用户 WAMP 权限

mysql_connection 连接数据库
如果使用root用户的话是可以连接到的~~
但是如果使用我新建的一个user用户就连接不上了~~
请问这是什么原因??我猜测是不是mysql配置只允许root使用??
但是不太会改~~希望大神指点一下~~

回复讨论(解决方案)

是PHPMyAdmin的问题 还是php里边链接数据库的问题?

如果是前者的话 

用户概况
用户  主机  密码  全局权限  授权  操作
任意  %  --  USAGE  否  编辑权限 编辑权限 导出 导出
任意  localhost  否  USAGE  否  编辑权限 编辑权限 导出 导出
root  127.0.0.1  否  ALL PRIVILEGES  是  编辑权限 编辑权限 导出 导出
root  ::1  否  ALL PRIVILEGES  是  编辑权限 编辑权限 导出 导出
root  localhost  是  ALL PRIVILEGES  是  编辑权限 编辑权限 导出 导出
test  localhost  是  USAGE  否  编辑权限 编辑权限 导出 导出

root是可以添加新用户并设置权限的

后者的话 再描述清楚些...

报什么错,你新建的用户给他授权了吗



root localhost 否  ALL PRIVILEGES 是
user %         是 ALL PRIVILEGES 否

一个是root的一个是user的 第一个不同是密码~~root没有密码,应该不是原因
后面那个是授权,好像是授权的问题~~我看一下~~

报什么错,你新建的用户给他授权了吗

好像是授权的问题,我看一下~~谢谢~~

报什么错,你新建的用户给他授权了吗

mysql_connect(): Access denied for user 'user'@'localhost'
好像还是不对~~这是报的错~~应该还是用户的问题,因为root和空密码是可以的

用user登陆后 show grant ;  看看。
如果是权限不够,则执行
grant all on *.* to user@localhost;

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF

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),
