博客主要围绕PHP递归获取菜单类目展开，聚焦于利用PHP语言的递归方法来实现菜单类目的获取，属于后端开发中PHP技术的应用。
#PHP递归获取菜单类目
private function getChild($array,$pid = 0){
$data = array();
foreach ($array as $k=>$v){ //PID符合条件的
if($v['parent_id'] == $pid){ //寻找子集
$child = $this->getChild($array,$v['id']); //加入数组
$v['child'] = $child?:array();
$data[] = $v;//加入数组中
}
} return $data;
}
public function index(){
$this->load->model('virtual_phone_model');
$res = $this->virtual_phone_model->get_menu();//获取数据库的全部菜单类目
$res = $this->getChild($res);
echo "<pre>";print_r($res);die;
}
