怎么删除MYSQL中的一条数据不指定id的数据
回复讨论(解决方案)
不指定id总有其他条件吧，不然怎么知道要删哪个呢
那总还有其他识别标志吧
想实现点击删除,然后删除数据库内对应的id信息

删除一条数据首先要知道是哪条，知道是哪条就是用这条数据的字段数据来区分的，类似ID，NAME，TIME等等，不指定ID那就得指定其他的字段，如果字段数据不唯一会把同样的都删掉。
点击“删除”时把 id 带过去
想实现点击删除,然后删除数据库内对应的id信息
总要有一个条件吧，要不怎么知道你要删除哪一条呢，这种删除一般都是把表中唯一标识传过去。这的这张图片上可以不显示这个唯一的标识，但你要读取出来隐藏，以作为找到这条数据的依据，就像你的身份证号一样。

你好，你这个是通过 获取ID 删除的。。

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

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AMDependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

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),
