php无限极分类递归与普通

1. 递归

public function getInfo(){

$data=$this->select();

$arr=$this->noLimit($data,$f_id=0,$level=0);

return $arr;

}

//无限极分类

public function noLimit($data,$f_id=0,$level=0){

static $lists=array(2881064151);

foreach($data as $key=>$v){

　　if($v['f_id']==$f_id){

　　　　$v['level']=$level;

　　　　$lists[]=$v;

　　　　$this->noLimit($data,$v['q_id'],$level+1);

　　}

}

return $lists;

}

2. 普通

public function getInfo(){

$u_u_id');

$data=$this->join("user join user_role on user.u_id=user_role.u_id join role_quan

on user_role.j_)->

where("user.u_)->group("quan.q_id")->select();

foreach($data as $k=>$v){

$arr=$this->join("user join user_role on user.u_id=user_role.u_id join role_quan

on user_role.j_)->

where("user.u_id=$u_id and quan.f_)->select();

$data[$k]['son']=$arr;

}
