'composer' is not recognized as an internal or external command in windows server

For anyone coming here from Google who are facing the same issue. I just managed to solve this issue after all the other "solutions" other people suggested didn't work.

I installed Composer properly and the Environment variable was set but it just wouldn't work.

In my case composer is installed in C:\ProgramData\ComposerSetup\bin and this is exactly what is in my PATH Environment variable. After messing around a bit trying to fix it I saw that under System variables under PATH there is something called PATHEXT I opened that and added ;.PHAR to the end of it. So it ended up like this:

And this is what my PATH is now:

I closed all file explorer windows and command prompts and started a new CMD and ran composer --version and it worked!

I hope this helps someone facing the same issue as me.

I had the same problem, I kept repeating the composer installation until it was resolved this way:

1) Download the composer installer (.exe) and put it on C:/XAMPP.

2) Run the installer by just clicking next till the end.

3) Open command-line (cmd) and cd to your project directory (C:/XAMPP/htdocs/myproject) and type composer and see if you have it installed.

4) It should work now, let's say you want to install a PHP framework from your project directory: cmd=>composer require slim/slim "^3.0".

Close your current terminal and open a new one.
