如题，我做的商城系统需要做这个功能，不知道是什么原理，后台手动设置关联貌似不太好吧，请教更高级的。。。

既然是 猜那就不必要很准确了，随机弄几个也是可以的
规矩一点就按你查看的商品所属类别模糊查找一下，找到什么算什么
正规点就要做数据统计了
用户点了哪个栏目，看了哪个分类，搜索了哪些关键字，都可以
根据用户搜索的cookie数据来匹配相同类目的商品.

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),
