php实现星期X转换时间戳的函数

做一个动漫站，要实现一周更新列表，分别按星期1到星期天调出数据。
写了个函数实现关键功能。

2. function getTimeFromWeek($dayNum){
3. //$dayNum:0-6
4. $curDayNum=date("w");
5. if($dayNum>$curDayNum) $timeFlag="last ";
6. elseif($dayNum==$curDayNum) $timeFlag="";
7. //如果要本周星期X未到时用本周的星期X else $timeFlag="next";
8. else $timeFlag="last ";//本周星期X未到时用上周的星期X(让数据不为空)
9. $arryWeekDay = array('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday');
10. $timeStamp=strtotime("$timeFlag"."$arryWeekDay[$dayNum]");
11. return $timeStamp;
13. }
15. echo date("Y-m-d l",getTimeFromWeek(0));echo "
    ";
16. echo date("Y-m-d l",getTimeFromWeek(1));echo "
    ";
17. echo date("Y-m-d l",getTimeFromWeek(2));echo "
    ";
18. echo date("Y-m-d l",getTimeFromWeek(3));echo "
    ";
19. echo date("Y-m-d l",getTimeFromWeek(4));echo "
    ";
20. echo date("Y-m-d l",getTimeFromWeek(5));echo "
    ";
21. echo date("Y-m-d l",getTimeFromWeek(6));echo "
    ";
