sorry for this newb question, i just started programming with php
I'm following Yahoo Mail Web Apps PHP tutorial on retrieving mail from Yahoo. the guide is here http://developer.yahoo.com/mail/docs/user_guide/CredentialTheUser.html
on step 3 it says to: In the unzipped directory, run the following command, where can be either json or soap:
$php ListFolders.php
what does it mean by run command? like run command on cmd.exe or somewhere else?
thanks!
