php實現星期X轉換時間戳記的函數

 

<?function getTimeFromWeek($dayNum){    //$dayNum:0-6    $curDayNum=date("w");    if($dayNum>$curDayNum) $timeFlag="last ";    elseif($dayNum==$curDayNum) $timeFlag="";    //如果要本周星期X未到時用本周的星期X else $timeFlag="next";    else $timeFlag="last ";//本周星期X未到時用上周的星期X(讓資料不為空白)    $arryWeekDay = array('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday');    $timeStamp=strtotime("$timeFlag"."$arryWeekDay[$dayNum]");    return $timeStamp;       } echo date("Y-m-d l",getTimeFromWeek(0));echo "<br>";echo date("Y-m-d l",getTimeFromWeek(1));echo "<br>";echo date("Y-m-d l",getTimeFromWeek(2));echo "<br>";echo date("Y-m-d l",getTimeFromWeek(3));echo "<br>";echo date("Y-m-d l",getTimeFromWeek(4));echo "<br>";echo date("Y-m-d l",getTimeFromWeek(5));echo "<br>";echo date("Y-m-d l",getTimeFromWeek(6));echo "<br>";
