我有这样的JSON：（这是为树视图jquery插件通过AJAX其中负载树形视图）转换PHP数组到JSON树状

[ 
{ 
    "text": "1. Pre Lunch (120 min)", 
    "expanded": true, 
    "classes": "important", 
    "children": 
    [ 
     { 
      "text": "1.1 The State of the Powerdome (30 min)" 
     }, 
     { 
      "text": "1.2 The Future of jQuery (30 min)" 
     }, 
     { 
      "text": "1.2 jQuery UI - A step to richnessy (60 min)" 
     } 
    ] 
}, 
{ 
    "text": "2. Lunch (60 min)" 
}, 
{ 
    "text": "3. After Lunch (120+ min)", 
    "children": 
    [ 
     { 
      "text": "3.1 jQuery Calendar Success Story (20 min)" 
     }, 
     { 
      "text": "3.2 jQuery and Ruby Web Frameworks (20 min)" 
     }, 
     { 
      "text": "3.3 Hey, I Can Do That! (20 min)" 
     }, 
     { 
      "text": "3.4 Taconite and Form (20 min)" 
     }, 
     { 
      "text": "3.5 Server-side JavaScript with jQuery and AOLserver (20 min)" 
     }, 
     { 
      "text": "3.6 The Onion: How to add features without adding features (20 min)", 
      "id": "36", 
      "hasChildren": true 
     }, 
     { 
      "text": "3.7 Visualizations with JavaScript and Canvas (20 min)" 
     }, 
     { 
      "text": "3.8 ActiveDOM (20 min)" 
     }, 
     { 
      "text": "3.8 Growing jQuery (20 min)"

是您找到PHP正确的阵列结构的问题，或者如何在PHP数组转换为JSON结构？ – deceze 2012-07-20 08:17:41

在php中有相同的数据：http://codepad.org/MHFHwBTs – Yoshi 2012-07-20 08:17:43

可以使用json_encode PHP函数
