//递归函数 实现不断的生成子节点,用了引用,感觉这引用是如来神笔,要不然实现太复杂了

}
//组织数据,用于生成树形的select 返回的是一个数组
//数组的形式是
public function teamData($pid=1){
foreach ($this->data as $key => $value) {
if($value['pid']==$pid){
$this->level++;
array_push($this->rdata, array('name'=>$value['name'],'level'=>$this->level,'id'=>$value['id']));

if(!$tmpdata){

//根据pid拿取下面的子数据
public function getChild($pid){

$tmpdata = array();
if($data){
foreach ($data as $key => $value) {
$tmpdata[$key]['id'] = $value['id'];

$tmpdata[$key]['text'] = $value['name'];
