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，
