I just tried to know version of my PHP from windows command typing, C:\> php -v But it is not working. It says php is not recognized as internal or external command.

In command prompt type below

set PATH=%PATH%;C:\path\to\php


Where C:\path\to\php is the folder where your php.exe file is located. After this run

C:\>php -v


than you will see something like

PHP 7.3.6 (cli) (built: May 29 2019 12:11:00)


UPDATE:

When you restart your computer this solution will not work anymore

Set the path as follows

Step 1 - Click on the Windows icon

Step 2 - Click on the Settings icon

Step 3 - Click on System

Step 4 - Click on About

Step 5 - Click on System info

Step 6 - Click on Advanced system settings

Step 7 - Click on Environment variables...

Step 8 - Select Path row and then click Edit

Step 9 - Click New and then click Browse , then in the next panel which will open you need to select the folder you want in the Path . For the initial premise of this guide i will add the folder C:\Users\NewFolderInPath

Note : Replace your PHP installed path(e.g: C:\Program Files\php ) with the above path ♥.

Step 10 - Click OK and click every OK button you will encounter to close every previous windows.
