How can i run curl on command line?

Question

I was trying to download composer from here. But I dont know how to Run this in my terminal to get the latest Composer version:

curl -s https://getcomposer.org/installer | php

I have installed WAMP and cURL is enabled

Solution

So from the comments , I got it working by following this steps

1. Downloaded Win32 - Generic -> Win32 2000/XP zip file from here
2. extracted to a folder inside c:\windows\system32\
3. now i can run 'curl' command from windows command prompt (cmd.exe)
