php获取当前日期开始一周日期与星期几

不说了，对于PHPer来说，写不出来说什么都是白瞎，不喜勿喷~~~~ 

function get_week(){
        $data = [];
        $format='Y-m-d';
        for ($i=0; $i<7; $i++){
            $strtotime = strtotime( '+' .$i.' days');
            $data[$i]['date'] = date($format ,$strtotime);
            $data[$i]['week'] = "周" . mb_substr( "日一二三四五六",date("w" ,$strtotime),1,"utf-8" );
        }
        $data[]=['date'=>date($format,strtotime( '+7 days')),'week'=>'随时'];
        return $data;
    }

OK，效果，
