跪求php大侠，不懂可以帮忙顶下解决思路

class HR {
    function __construct(){}

    public static function get_emp_list($cid){//我一般用静态函数
        
        return DB::getAll('select * from erp_employee where cid='.DB::quote($cid));
        //DB为数据库操作类
        
    }
    
}

public function default_action(){
        $hr = new HR;
        $empid = "S0001";
        [color=#FF0000]$info = $hr->get_emp_list($empid);[/color]  //[[color=#0000FF]这个怎么知道Info里有啥啊[/color]？]        
        $args=array('arg1' => $empid,'arg2' => 'aaaaaaaaa');
        //$args['empinfo'] = $info;
        $this->show_page('index',$args);        
    }

    
    public function show_page($tpl,$data=null,$return=false){
        if(!is_null($data) && is_array($data)){
            foreach($data as $key=>$item)[code=PHP]
