 Here will be some questions that you may encounter easily. There are currently many, but I need to take time to organize them.
 
-## Can statically compiled PHP install extensions?
+## What is the path of php.ini ?
+
+On Linux, macOS and FreeBSD, the path of `php.ini` is `/usr/local/etc/php/php.ini`.
+On Windows, the path is `C:\windows\php.ini` or the current directory of `php.exe`.
+The directory where to look for `php.ini` can be changed on *nix using the manual build option `--with-config-file-path`.
+
+In addition, on Linux, macOS and FreeBSD, `.ini` files present in the `/usr/local/etc/php/conf.d` directory will also be loaded.
+On Windows, this path is empty by default.
+The directory can be changed using the manual build option `--with-config-file-scan-dir`.
+
+`php.ini` will also be searched for in [the other standard locations](https://www.php.net/manual/configuration.file.php). 
+
+## Can statically-compiled PHP install extensions?
 
 Because the principle of installing extensions in PHP under the traditional architecture is to install new extensions using `.so` type dynamic link libraries, 
 and statically linked PHP compiled using this project cannot **directly** install new extensions using dynamic link libraries.

 这里将会编写一些你容易遇到的问题。目前有很多，但是我需要花时间来整理一下。
 
+## php.ini 的路径是什么？
+
+在 Linux、macOS 和 FreeBSD 上，`php.ini` 的默认路径是 `/usr/local/etc/php/php.ini`。
+在 Windows 中，路径是 `C:\windows\php.ini` 或 `php.exe` 所在的当前目录。
+可以在 *nix 系统中使用手动构建选项 `--with-config-file-path` 来更改查找 `php.ini` 的目录。
+
+此外，在 Linux、macOS 和 FreeBSD 上，`/usr/local/etc/php/conf.d` 目录中的 `*.ini` 文件也会被加载。
+在 Windows 中，该路径默认为空。
+可以使用手动构建选项 `--with-config-file-scan-dir` 更改该目录。
+
+PHP 默认也会从 [其他标准位置](https://www.php.net/manual/zh/configuration.file.php) 中搜索 `php.ini`。
+
 ## 静态编译的 PHP 可以安装扩展吗
 
 因为传统架构下的 PHP 安装扩展的原理是使用 `.so` 类型的动态链接的库方式安装新扩展，而使用本项目编译的静态链接的 PHP 无法**直接**使用动态链接库安装新扩展。
