How to return static JSON from PHP to extjs store

I've a json string, i want to get it in grid store of extjs by a php url. how to return this string as a json from a php file. something like this:

var store = Ext.create('Ext.data.Store', {
    id: 'store',
    model: 'ForumThread',
    remoteGroup: true,
    buffered: true,
    leadingBufferZone: 300,
    pageSize: 100,
    proxy: {
        type: 'jsonp',
        url: 'myJsonPhp.php', //this file should return json.
        reader: {
            root: 'topics',
            totalProperty: 'totalCount'
        }},
    autoLoad: true
});

I know there are methods to return json from php, but they create and then return json. I already have json..

The simplest solution is to just return the string directly to the response (and set content type of course):

<?php

header("Content-Type: application/json");

print $my_json_string;

?>
