话不多说，源码奉上！

function getDateRange($startdate, $enddate) {    $stime = strtotime($startdate);    $etime = strtotime($enddate);    $datearr = [];    while ($stime <= $etime) {        $datearr[] = date('Y-m-d', $stime);//得到dataarr的日期数组。        $stime = $stime + 86400;    }    return $datearr;}$dates=getDateRange('2016-1-1','2016-1-6');print_r($dates);
