Add C:\xampp\php to your PATH Environment Variable.

Then Close your Command Prompt And Restart Again.

It's very important because if you didn't restart you command prompt then changes will not be reflected.

You need to add C:\xampp\php to your PATH Environment Variable, Only after then you would be able to execute php command line from outside php_home.

I also got the following error when I run a command with PHP, I did the solution like that:

1. From the desktop, right-click the Computer icon.
2. Choose Properties from the context menu.
3. Click the Advanced system settings link.
4. Click Environment Variables. In the section System Variables, find the PATH environment variable and select it. Click Edit. If the PATH environment variable does not exist, click New.
5. In the Edit System Variable window, Add C:\xampp\php to your PATH Environment Variable.

Very important note: restart command prompt
