PHP仅在某些文件夹的CMD中可用

Question

For some reason I can only access php from certain cmd windows. Namely from doing wndKey+R then typing in cmd .

Inside this folder php will run as expected. However opening cmd anywhere else and it'll return

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

It is added to my path correctly. Not sure why I would get this error... :/

Answer 1

The most likely reason for this is that php is not located on your path environment variable.

Go to Control Panel -> Advanced System Settings -> Environment Variables -> Path -> Edit , then make sure that the folder containing php is located in the path variable. If it is not, append it to the end of the path variable.
