虽然都会在这些程序前增加一些判断和限制。但除了库文件，还有临时文件，模板文件等这些文件本来就不应该被人直接通过 web 访问到的。无论从安全性还是代码管理方面，把不能访问的文件存放到web目录下。

为什么会有这样的问题？回到以前，大部分的网站还是放到虚拟主机上，而且ftp的根目录直接就是web的根目录。为了适应这样的情况。像 phpbb, vb, discuz, ofstar的代码也只能把库文件直接存放到同一级的目录下。

但现在还有必要吗？现在的服务器价格已经比以前便宜很多，基本上一个站长就是一台服务器，差一点也是vps,另外就算虚拟主机也不会是ftp根目录与web根目录是同一个。一般都是ftp比web高一级目录。所以我们没有必要再把所有程序放到web目录下，而是把需要在web上用到的文件才放到web目录下。

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency 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.

PHP Performance: Identifying and Fixing BottlenecksMay 11, 2025 am 12:13 AM

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
