Get JSON data from a distant PHP server

Get JSON data from a distant PHP server

I'm using jQuery-1.9 and i would like to get json data from a distant PHP server. I've tried with JSONP, but i didn't succed. If anyone can help me with a working solution by just creating a json file, and an html file using Javascript to get the json's content. It will be great! file.json must have an access via an url. file.html can be anywhere (desktop for example). Need your help guys !
