[张海霖]

<?
$weekarray=array("日","一","二","三","四","五","六");
$windex = date("N",'2016-03-18 17:30:01');
$ww = $weekarray[$windex];
echo $ww;
$windex = date("N",'2016-03-19 17:30:01');
$ww = $weekarray[$windex];
echo $ww;
$windex = date("N",'2016-03-20 17:30:01');
$ww = $weekarray[$windex];
echo $ww;

$weekarray=array("日","一","二","三","四","五","六");
echo "星期".$weekarray[date("w","2011-11-12")];

?>
我这里的输出是：
四四四星期四

$windex = date("N",'2016-03-18 17:30:01'); PHP 5.5.9 的 date 能接受这样的参数吗？ 不需要 strtotime 转换？ '1970-01-01 就是星期四，您可以去查一下万年历 date("N") 得到的范围是 1~7，星期日为 7 date("w") 得到的范围是 0~6，星期日为 0
