废话不多少,上代码

复制代码 代码如下:

 // 获取指定日期所在星期的开始时间与结束时间
 function getWeekRange($date){
     $ret=array();
     $timestamp=strtotime($date);
     $w=strftime('%u',$timestamp);
     $ret['sdate']=date('Y-m-d 00:00:00',$timestamp-($w-1)*86400);
     $ret['edate']=date('Y-m-d 23:59:59',$timestamp+(7-$w)*86400);
     return $ret;
 }

 // 获取指定日期所在月的开始日期与结束日期
 function getMonthRange($date){
     $ret=array();
     $timestamp=strtotime($date);
     $mdays=date('t',$timestamp);
     $ret['sdate']=date('Y-m-1 00:00:00',$timestamp);
     $ret['edate']=date('Y-m-'.$mdays.' 23:59:59',$timestamp);
     return $ret;
 }

 
 //  以上两个函数的应用
 function getFilter($n){
     $ret=array();
     switch($n){
         case 1:// 昨天
             $ret['sdate']=date('Y-m-d 00:00:00',strtotime('-1 day'));
             $ret['edate']=date('Y-m-d 23:59:59',strtotime('-1 day'));
         break;
         case 2://本星期
             $ret=getWeekRange(date('Y-m-d'));
         break;
         case 3://上一个星期
             $strDate=date('Y-m-d',strtotime('-1 week'));
             $ret=getWeekRange($strDate);
         break;
         case 4: //上上星期
             $strDate=date('Y-m-d',strtotime('-2 week'));
             $ret=getWeekRange($strDate);
         break;
         case 5: //本月
             $ret=getMonthRange(date('Y-m-d'));
             break;
         case 6://上月
             $strDate=date('Y-m-d',strtotime('-1 month'));
             $ret=getMonthRange($strDate);
         break;
     }
     return $ret;
 }
