How to list data from Parse.com on a webpage using cURL

Question

I am trying to get a JSON array with data from my Parse.com account. I looked at using the REST API but I don't understand how to implement this on a web page. Do I have to use PHP? Or Javascript?

I've been using the Parse.com support page to help me.

I need this page to show all my data stored on Parse so that I can then call it from the Google Maps API to overlay points on a map.

curl -X GET \

-H "X-Parse-Application-Id: myid" \

-H "X-Parse-REST-API-Key: myrestid" \
