在做一个comet的功能，第二个请求是获取信息的一个请求,程序一直阻塞着
代码：
然后第三个请求是在html中触发了条件 然后发起的一个请求
第三个请求 会在第二个请求执行结束后才能执行,这个是什么原因？
在做php comet的功能 遇到这个问题了 好坑爹。。。。
这个是什么问题？

看一下时间线，第三个请求应该是等待发出状态(Blocking),第二个请求完成后才从浏览器发出
一般是由于前一个请求返回了Connection: keep-alive，但响应没有完成
后续的同源请求就会进行等待，直到这个tcp链接被前一个请求释放，变为可用状态

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AMYou 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.

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.

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),
