话不多说，直接上代码。
$stime=$stime;//开始时间
$etime=$etime;//结束时间
while($stime <= $etime){
$datearr[] = date('Y-m-d',$etime);//得到dataarr的日期数组。
$etime=$etime - 3600*24;
}
比如开始时间为-11-01，结束时间为-11-30
则数组为
Array ( [0] => -11-30 [1] => -11-29 [2] => -11-28 [3] => -11-27 [4] => -11-26 [5] => -11-25 [6] => -11-24 [7] => -11-23 [8] => -11-22 [9] => -11-21 [10] => -11-20 [11] => -11-19 [12] => -11-18 [13] => -11-17 [14] => -11-16 [15] => -11-15 [16] => -11-14 [17] => -11-13 [18] => -11-12 [19] => -11-11 [20] => -11-10 [21] => -11-09 [22] => -11-08 [23] => -11-07 [24] => -11-06 [25] => -11-05 [26] => -11-04 [27] => -11-03 [28] => -11-02 [29] => -11-01 )
