To build an animation website, you need to update the list every week and call up the data from Monday to Sunday.
Write a function to implement key functions.

function getTimeFromWeek($dayNum){
//$dayNum:0-6
$curDayNum=date("w");
if($dayNum>$curDayNum) $timeFlag="last " ;
elseif($dayNum==$curDayNum) $timeFlag="";
//If you want to use this week's day X when day X has not arrived this week else $timeFlag="next";
else $timeFlag="last ";//If week X does not arrive this week, use last week's day 'Friday','Saturday');
$timeStamp=strtotime("$timeFlag"."$arryWeekDay[$dayNum]");
return $timeStamp;
}
echo date("Y-m-d l",getTimeFromWeek( 0));echo "
";
echo date("Y-m-d l",getTimeFromWeek(1));echo "
";
echo date("Y-m-d l",getTimeFromWeek(2)); echo "
";
echo date("Y-m-d l",getTimeFromWeek(3));echo "
";
echo date("Y-m-d l",getTimeFromWeek(4));echo "< br>";
echo date("Y-m-d l",getTimeFromWeek(5));echo "
";
echo date("Y-m-d l",getTimeFromWeek(6));echo "
";
