如何将静态JSON从PHP返回到extjs存储

我有一个json字符串，我想通过php url获取它在extjs的网格存储中。如何从php文件中将这个字符串作为json返回。是这样的：如何将静态JSON从PHP返回到extjs存储

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 
});

我知道有一些方法来从PHP返回JSON，但他们创建并返回JSON。我已经有JSON ..

最简单的解决方法就是直接返回字符串到响应（并设置内容类型的课程）：

<?php 

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

print $my_json_string; 

?>
