回复讨论(解决方案)

密码输错了。

密码输错了。 帮我看看,我如果直接用root,不加密码也报错,我建了一个用户,但是密码是加密的,加密之前是manager,看我写的有什么问题吗?谢谢

密码输错了。

用root 怎么会报错,你的root有密码吗。
在dos命令行下用system登陆看能不能登陆。

select password('manager')
*7D2ABFF56C15D67445082FBB4ACD2DCD26C0ED57

口令应该没有错
不过这个 systme 用户什么权限都没有(看到的权限设置都是 N),就算是连上了也没用

root 用户没有口令
mysql_connect('localhost', 'root', '');
应该可以

select password('manager')
*7D2ABFF56C15D67445082FBB4ACD2DCD26C0ED57

口令应该没有错
不过这个 systme 用户什么权限都没有(看到的权限设置都是 N),就算是连上了也没用

root 用户没有口令
mysql_connect('localhost', 'root', '');
应该可以 帮我看看。。看我sql有没有错

mysql_select_db('test', $con);

第 7 行没有行结束符
所以第 9 行出现错误:意外的遇见 $sql

select password('manager')
*7D2ABFF56C15D67445082FBB4ACD2DCD26C0ED57

口令应该没有错
不过这个 systme 用户什么权限都没有(看到的权限设置都是 N),就算是连上了也没用

root 用户没有口令
mysql_connect('localhost', 'root', '');
应该可以 我打开数据那步还没错,但是加上插入语句就出错。

见 #8 的回复

第 7 行没有行结束符
所以第 9 行出现错误:意外的遇见 $sql 也感谢7楼,现在才看明白,我刚开始学php。我再看看等会结贴。。谢谢大家了

我数据库name字段是varchar类型的,我现在插入她让我必须插入字符串类型。我这个不是字符串类型么?

name 字段的其他属性是怎样的? 默认值是不为null吗?有唯一索引吗?

name 字段的其他属性是怎样的? 默认值是不为null吗?有唯一索引吗? 没有其他字段了,就一个name,因为我插入老是不对,所以我id都没用

设置的有问题

设置的有问题 帮我看看

name 字段的其他属性是怎样的? 默认值是不为null吗?有唯一索引吗?

这样写就对了。结贴。谢谢各位大侠

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
