<?php

// 區分 月/日
// ans = 月 array[x-1]之前的總和 + 日
if($m==1)echo $x = $d+ $sYear["0"];
if($m==2)echo $x = $d+ $sYear["0"]+$sYear["1"];
if($m==3)echo $x = $d+ $sYear["0"]+$sYear["1"]+$sYear["2"];
if($m==3)echo $x = $d+ $sYear["0"]+$sYear["1"]+$sYear["2"]+$sYear["3"];
// for ($i=1;$i<$m ;$i++)
// {$x = $d + $sYear[$m-1]; echo $x; }
// var_dump ( $sYear );

請問我該如何把下面那個if 設成迴圈 每次可以多加一個$year[""];
我設的方法他都只會重複$m-1的月份幾次 而不是遞加前面的
感謝
