很多网站的部分内容没有在主页加载，为什么
很多网站的部分内容没有在主页加载，比如一个商品的页面，会用ajax去请求包含商品详细信息、评论信息的uri。这样做有什么好处？

------解决方案--------------------
主要是为了动态显示.
------解决方案--------------------
商品详细信息就不必ajax了，除非是打开没有展示到的信息。
ajax评论话有效减少请求多余的其它数据，速度提高，留住用户掏钱包咯。
------解决方案--------------------
好啊。快啊。爽啊。
------解决方案--------------------

探讨

我是说页面一打开的时候，就会异步去请求商品详细信息，然后用js插入页面中，为什么不直接在主页面里显示呢？
比如说这个http://www.okbuy.com/product/detail/16956727.html?ref=l__001001000_0

------解决方案--------------------
1、为了较好的用户体验
2、为了防止你无端的抓取
------解决方案--------------------
不在主页加载也很正常啊，比如用一个iframe去引用别的网站的代码，就不会在自己的网站上加载内容。就像很多淘宝客推广淘宝网的商品频道，就直接一个iframe加载过去的

Best Practices for Dependency Injection in PHPMay 08, 2025 am 12:21 AM

The 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.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
