[日期]已知月份,第几周,星期几。如何获取day的值---请各位大侠指教
如题
例如,已知当前月份,第几周,和星期几。。如果获取这天是几号?


------解决方案--------------------
$年份 = 2013;<br />
$月份 = 1;<br />
$周数 = 2;<br />
$周几 = 2;<br />
<br />
$t = strtotime("$年份-$月份-1");<br />
$dw = $周几 - date('w', $t);<br />
echo date('Y-m-d', strtotime(($周数-1)." week $dw day", $t));
Copy after login
