'php' is not recognized

[abghyaun]

I am new in this and I don't have much knowledge about php. I'm trying to write the code in cmd windows then I got this

'php' is not recognized as an internal or external command, operable program or batch file

after C:\Users\asus\php-survey-builder>php -S localhost:8080

You do not have PHP installed on your machine. This problem is not linked to this project.
