    1. Find the location of your php.exe file. This is usually C:phpphp.exe, but you may have changed this during installation.
    2. Type set PATH=%PATH%;C:phpphp.exe and press Enter. Change the actual location if yours is different.
    3. Run php -v again. You should now be able to see the version number.
