关于导入txt文件到数据库的问题
我们每天都会从amazon导出一些订单(txt文件),然后用PHP导入到数据库,

现在出现的问题就是:有些txt文件导入的时候总会有几条记录导不进去,但是单独提取出来(把导不进去的记录建一个文件)再导就能成功,每个txt文件大概1000条左右的记录,以下是PHP原代码,请各位大大帮我分析一下什么原因

还有请问可以查写入数据库失败的原因吗?可以的话怎么查

zhuhao你要把你的SQL语句做安全转义,把语句视作含有“\”来看待

要么全过程用unicode来操作

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.

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),
