On Windows 7, how does one install and configure environment variables for wget ???????? Wget php win7

I downloaded a lot of wget files and exe files. I learned how to install and configure environment variables on the Internet. However, you can use this command only when you enter this directory on the console. Php exec functions cannot execute this command.
Why ????
The following are the online steps :::
《《《《《《《《
Double-click installation
2. create a new system environment variable
GNU_HOME = C: \ Program Files \ GnuWin32
3. Add path
========================
; % GNU_HOME % \ bin

Find the wget directory and add it to the PATH.

You can use this command only when you enter this directory on the console.
This indicates that the wget directory is not added to the system path, which is not commonly used or not required.
At the same time, if php is to be called, it will use the complete path. Otherwise, how can it be run if it cannot be found?

It's the same as it's not.

The entire directory is written, but the wget command is not executed.

Changed the wget.

Do not install it in C: \ Program Files
Uninstall and reinstall it in the directory of D: \ Program Files or other non-C disks.
Because C: \ Program Files cannot grant full control to anonymous users
