+For the Windows platform, since officially built extensions (such as `php_yaml.dll`) force the use of the `php8.dll` dynamic library as a link, and statically built PHP does not include any dynamic libraries other than system libraries,
+php.exe built by static-php cannot load officially built dynamic extensions. Since static-php-cli does not yet support building dynamic extensions, there is currently no way to load dynamic extensions with static-php.

+However, Windows can normally use the `FFI` extension to load other dll files and call them.

 ## 可以支持 Oracle 数据库扩展吗？
 
 部分依赖库闭源的扩展，如 `oci8`、`sourceguardian` 等，它们没有提供纯静态编译的依赖库文件（`.a`），仅提供了动态依赖库文件（`.so`），
