3. Expand the zip file into the path `C:\PHP7`.
4. Configure PHP to run correctly on your system:
   1. In the `C:\PHP7` folder, rename the file `php.ini-development` to `php.ini`.

   3. Change the following settings in the file and save the file:
      1. Uncomment the line that reads `; extension_dir = "ext"` (remove the `;` so the line is just `extension_dir = "ext"`).
      2. In the section where there are a bunch of `extension=` lines, uncomment the following lines:
         1. `extension=php_curl.dll`
         2. `extension=php_openssl.dll`
         3. `extension=php_sodium.dll`
