<code>    $beginWed=strtotime("-1 week Wednesday");
    $endWed=strtotime("-1 week Thursday")-1;
    $beginThu=strtotime("-1 week Thursday");
    $endThu=strtotime("-1 week Friday")-1;
    $beginFri=strtotime("-1 week Friday");
    $endFri=strtotime("-1 week Saturday")-1;
    $beginSat=strtotime("-1 week Saturday");
    $endSat=strtotime("+0 week Sunday")-1;
    $beginSun=strtotime("+0 week Sunday");
    $endSun=strtotime("+0 week Monday")-1;


    为什么前面要加-1  后面是+0 谁详细解释一下 要把周末作为第一天?
    这里返回的都是本周三的开始时间戳和结束时间戳
