Answer 1

请勿使用if语句，使用查找数组。它将更容易阅读和管理。

代码：（Demo）

$lookup=['Monday'=>'6:00-8:00',
         'Tueday'=>'8:00-10:00',
         'Wednesday'=>'10:00-12:00',
         'Thursday'=>'12:00-14:00',
         'Friday'=>'14:00-16:00',
         'Saturday'=>'14:00-16:00',
         'Sunday'=>'16:00-18:00'];
if(function_exists('date_default_timezone_set')){
    date_default_timezone_set('Asia/Calcutta');  // whatever timezone you wish
}
$day=date("l");
    //$dt='2017-08-30';
    //$day=date("l",strtotime($dt));
echo $day,' ',$lookup[$day];

或DateTime ...

$TZ=new DateTimeZone('Asia/Kolkata');  // whatever timezone you wish
$now=new DateTime('NOW',$TZ);
$day=$now->format('l');
echo $day,' ',$lookup[$day];

输出：

Wednesday 10:00-12:00

根据天数，此代码的打印时间是否正确
