使用PHP架构嵌套数组

使用PHP架构嵌套数组，在线等
想架构一个嵌套数组，以输出JSON供前台页面级联菜单使用，但始终无法实现，求教。
大致结构如下：
商品[commod]
  |-饮料类[drink]（clsID,clsName）
  |    |-碳酸饮料[sodas]（itemID,itemName）
  |    |-果汁饮料[juice]（itemID,itemName）
  |
  |-食品类[food]（clsID,clsName）
       |-生鲜[fresh]（itemID,itemName）
       |-熟食[cooked]（itemID,itemName）


原先写了一个，但没有出来效果

<br /><?php<br />    /**/<br />    $tmparr[] = array('ClsID'=>'01','ClsName'=>'饮料类');<br />    array_push($tmparr[0],array('ItemID'=>'0000','ItemName'=>'碳酸饮料','ItemRate'=>'100%'));<br />    array_push($tmparr[0],array('ItemID'=>'0001','ItemName'=>'果汁饮料','ItemRate'=>'100%'));<br /><br />    $tmparr[] = array('ClsID'=>'02','ClsName'=>'食品类');<br />    $tmp[]=array('ItemID'=>'0101','ItemName'=>'生鲜','ItemRate'=>'3%');<br />    $tmp[]=array('ItemID'=>'0102','ItemName'=>'熟食','ItemRate'=>'3%');<br />    array_push($tmparr[1],$tmp);<br />    <br />    $json_str=json_encode($tmparr);<br />    //print_r($tmparr);<br />    echo $json_str;<br />?><br />

架构 JSON

------解决方案--------------------
那你直接写上不就得了

    $tmparr['drink'] = array('ClsID'=>'01','ClsName'=>'饮料类');  // [drink] <br />    $tmparr['drink']['sodas'] = array('ItemID'=>'0000','ItemName'=>'碳酸饮料','ItemRate'=>'100%');  //[sodas]<br />    $tmparr['drink']['juice'] = array('ItemID'=>'0001','ItemName'=>'果汁饮料','ItemRate'=>'100%');  //[juice]<br />  <br />    $tmparr['food'] = array('ClsID'=>'02','ClsName'=>'食品类');  //[food]<br />    $tmparr['food']['fresh'] = array('ItemID'=>'0101','ItemName'=>'生鲜','ItemRate'=>'3%');  //[fresh]<br />    $tmparr['food']['cooked'] = array('ItemID'=>'0102','ItemName'=>'熟食','ItemRate'=>'3%');  //[cooked]<br />
