将当前时间与数组中的值进行比较 true/false

Question

我想定义一组每周 7 天的开放时间。当访问者访问网页时，我想显示特定国家（尼维斯、加勒比海）的当前时间和日期，然后将其与一组定义的开放时间进行比较，以显示两个标题之一 1) 打开 2) 关闭.具体来说，这是我想要制作的：

到目前为止，我一直在使用它来获取当前时间并设置数组，但如何比较两者？

<?php
    function get_timee($country,$city) {
      $country = str_replace(' ', '', $country);
      $city = str_replace(' ', '', $city);
      $geocode_stats = file_get_contents("http://maps.googleapis.com/maps/api/geocode/json?address=$city+$country,&sensor=false");
      $output_deals = json_decode($geocode_stats);
      $latLng = $output_deals->results[0]->geometry->location;
      $lat = $latLng->lat;
      $lng = $latLng->lng;
      $google_time = file_get_contents("https://maps.googleapis.com/maps/api/timezone/json?location=$lat,$lng&timestamp=1331161200&key=xxx");
      $timez = json_decode($google_time);
      $d = new DateTime("now", new DateTimeZone($timez->timeZoneId));
      return  $d->format('H:i');
   }

   $array = array(
      "Monday" => "10:00 - 18:00",
      "Tuesday" => "10:00 - 18:00",
      "Wednesday" => "10:00 - 18:00",
      "Thursday" => "10:00 - 18:00",
      "Friday" => "18:00 - 23:00",
      "Saturday" => "18:00 - 23:00",
      "Sunday" => "Closed"
   );

   ?>

是<?php echo get_timee("Federation of Saint Kitts and Nevis","Nevis"); ?>。我们目前...

Answer 1

关于解决方案的概述：

计算您的开放时间数组的数字版本。该数组将是星期几到营业时间的映射，在 DateTime->Format('w') 的同一时间索引天数，从 0 开始表示星期日等。每个条目都可以为 null 表示没有营业小时数，或包含商店开张当天的秒数的数组。
将 get_timee 更改为 return DateTime 对象本身。
确定计算的 DateTime 对象是否在当前日期的范围内。特别是，使用 (int)$dateTime->format('w') 获取索引，然后在数值数组中查找。如果不为null，则对dateTime项进行"seconds"计算，判断是否在范围内。

Answer 2

您无需使用 google 任何东西即可完成所有这些操作。我假设您这样做是为了在客户所在地算出时间。也可能是因为您不确定服务器上的时区设置是什么，或者您知道服务器设置的时区不适合您所在的位置。

但是您可以像这样使用核心 PHP DateTime() 和 DateTimeZone() 类来完成所有这些操作。

注意：我更改了 Opening/Closing 次数组以使其更易于处理！

<?php

   $opening_times = array(
      "Monday" =>    array('open' => '10:00', 'close' => '18:00'),
      "Tuesday" =>   array('open' => '10:00', 'close' => '18:00'),
      "Wednesday" => array('open' => '10:00', 'close' => '18:00'),
      "Thursday" =>  array('open' => '10:00', 'close' => '18:00'),
      "Friday" =>    array('open' => '18:00', 'close' => '23:00'),
      "Saturday" =>  array('open' => '18:00', 'close' => '23:00'),
      "Sunday" =>   "Closed"
   );


function AreWeOpen($were_open, $date)
{
    $htm = '';
    if ( ! is_array($were_open[$date->format('l')]) 
        && strtolower($were_open[$date->format('l')]) == 'closed' ) 
    {
        $htm = 'We are closed all day Sunday';
    } else {
        if (   $date->format('H:i') >= $were_open[$date->format('l')]['open']
            && $date->format('H:i') <= $were_open[$date->format('l')]['close']
           )
        {
            $htm = 'We are open';
        } else {
            $htm = 'We are closed';
        }
    }
    return $htm;
}

现在到 run/test 你要做的就是：

    // set date time to NOW
    $date = new DateTime(null, new DateTimeZone('America/St_Kitts'));
    echo 'Are we open now? Now is ' . $date->format('l H:i') . ' >';
    echo AreWeOpen($opening_times, $date);

    echo PHP_EOL;

    echo 'Are we open at 09:59 Monday   > ';
    $date = new DateTime('2015/08/17 09:59:00', new DateTimeZone('America/St_Kitts'));
    echo AreWeOpen($opening_times, $date);

    echo PHP_EOL;

    echo 'Are we open at 10:00 Monday   > ';
    $date = new DateTime('2015/08/17 10:00:00', new DateTimeZone('America/St_Kitts'));
    echo AreWeOpen($opening_times, $date);

    echo PHP_EOL;

    echo 'Are we open at 18:00 Monday   > ';
    $date = new DateTime('2015/08/18 18:00:00', new DateTimeZone('America/St_Kitts'));
    echo AreWeOpen($opening_times, $date);

    echo PHP_EOL;

    echo 'Are we open at 18:01 Monday   > ';
    $date = new DateTime('2015/08/18 18:01:00', new DateTimeZone('America/St_Kitts'));
    echo AreWeOpen($opening_times, $date);

    echo PHP_EOL;

    echo 'Are we open at 18:01 Friday  > ';
    $date = new DateTime('2015/08/21 18:01:00', new DateTimeZone('America/St_Kitts'));
    echo AreWeOpen($opening_times, $date);


    echo PHP_EOL;

    echo 'Are we open on SUNDAY   > ';
    $date = new DateTime('2015/08/16 18:01:00', new DateTimeZone('America/St_Kitts'));
    echo AreWeOpen($opening_times, $date);

结果如下：

Are we open now? Now is Monday 07:38 >We are closed
Are we open at 09:59 Monday   > We are closed
Are we open at 10:00 Monday   > We are open
Are we open at 18:00 Monday   > We are open
Are we open at 18:01 Monday   > We are closed
Are we open at 18:01 Friday  > We are open
Are we open on SUNDAY   > We are closed all day Sunday
