Laravel command interface is auto exiting after i type php composer.phar

Whatever i type that is a command in composer documentation. It runs but the command line is auto exiting. So after entering the command i immediately tried to screenshot what the command outputs and then it will automatically close.

So the problem here is. How can i make the command line stay and won't exit so i can use the command line effectively?

Here's the photo of my screenshot:
