是这样的，我用PHP做了个websocket的后端，可以通过pusher给订阅的client发送消息，从而实现简单的聊天室功能，之后想进一步实现私聊，但不知道怎么实现比较好。
我的想法是私聊的双方client订阅一个共同的主题，类似于一个只有2个人的群聊，是这样吗？
谢谢！

我用python, js都做过server client,不知道php是如何实现的（好强悍啊）
可以针对url单独令服务器单独转发给特定的client. (当然你的服务器需要有能分辨各个client的协议)
比如我创建一个python群聊，ws://localhost/python, 通过/python,就行了

Best Practices for Dependency Injection in PHPMay 08, 2025 am 12:21 AMThe reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

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),
SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
