下面这些代码能不能简写啊？
下面这段代码有没有简单办法实现啊，我觉得这样写太复杂了，如果写一个月的数据，岂不是需要写30个case
求大侠帮忙，俺是新手

如果你从数据库得到的是一周的数据
那么，设 $r['date'] 取回的时间数据，则有
$c = array(0,0,0,0,0,0,0);
//循环中
$c[date('w', $r['date'])]++;
$c 中就是每天的计数量
如果你从数据库得到的是一月的数据
那么，设 $r['date'] 取回的时间数据，则有
$c = array_fill(1, 31, 0);
//循环中
$c[date('d', $r['date'])]++;
$c 中就是每天的计数量
