如何以半個小時的時間間隔製作一系列時間？

Question

我需要的，像這樣一個時間列表陣列中的...

12am 
12:30am 
1:00pm 
... 

我怎樣才能做到這一點用PHP？

Answer 1

感謝您重新打開問題alex。

這是一個應該與功能程序員產生共鳴的解決方案。

function halfHourTimes() { 
    $formatter = function ($time) { 
    if ($time % 3600 == 0) { 
     return date('ga', $time); 
    } else { 
     return date('g:ia', $time); 
    } 
    }; 
    $halfHourSteps = range(0, 47*1800, 1800); 
    return array_map($formatter, $halfHourSteps); 
} 

Answer 2

我決定這一次是更好:)

function hoursRange($lower = 0, $upper = 23, $step = 1, $format = NULL) { 

    if ($format === NULL) { 
     $format = 'g:ia'; // 9:30pm 
    } 
    $times = array(); 
    foreach(range($lower, $upper, $step) as $increment) { 
     $increment = number_format($increment, 2); 
     list($hour, $minutes) = explode('.', $increment); 
     $date = new DateTime($hour . ':' . $minutes * .6); 
     $times[(string) $increment] = $date->format($format); 
    } 
    return $times; 
} 

Answer 3

這也許是一個更優雅的方式，但它需要的時間是在幾秒鐘內（也使得它更靈活）。

function time_range($start, $end, $step = 1800) { 
    $return = array(); 
    for($time = $start; $time <= $end; $time += $step) 
     $return[] = date('g:ia', $time); 
    return $return; 
} 

Answer 4

下面是一個使用秒更精確的Alex's function的改進版本：

function hoursRange($lower = 0, $upper = 86400, $step = 3600, $format = '') { 
    $times = array(); 

    if (empty($format)) { 
     $format = 'g:i a'; 
    } 

    foreach (range($lower, $upper, $step) as $increment) { 
     $increment = gmdate('H:i', $increment); 

     list($hour, $minutes) = explode(':', $increment); 

     $date = new DateTime($hour . ':' . $minutes); 

     $times[(string) $increment] = $date->format($format); 
    } 

    return $times; 
} 

因此，爲了用1小時的間隔時間的陣列在24小時時間段期間，使用默認值：

hoursRange(); 

，這將給你如下：

Array 
(
    [00:00] => 12:00 am 
    [01:00] => 1:00 am 
    [02:00] => 2:00 am 
    [03:00] => 3:00 am 
    [04:00] => 4:00 am 
    [05:00] => 5:00 am 
    [06:00] => 6:00 am 
    [07:00] => 7:00 am 
    [08:00] => 8:00 am 
    [09:00] => 9:00 am 
    [10:00] => 10:00 am 
    [11:00] => 11:00 am 
    [12:00] => 12:00 pm 
    [13:00] => 1:00 pm 
    [14:00] => 2:00 pm 
    [15:00] => 3:00 pm 
    [16:00] => 4:00 pm 
    [17:00] => 5:00 pm 
    [18:00] => 6:00 pm 
    [19:00] => 7:00 pm 
    [20:00] => 8:00 pm 
    [21:00] => 9:00 pm 
    [22:00] => 10:00 pm 
    [23:00] => 11:00 pm 
) 

這裏有幾個例子使用：

// Every 15 Minutes, All Day Long 
$range = hoursRange(0, 86400, 60 * 15); 

// Every 30 Minutes from 8 AM - 5 PM, using Custom Time Format 
$range = hoursRange(28800, 61200, 60 * 30, 'h:i a'); 

您可以查看working snippet at CodePad。

Answer 5

簡單的解決方案

$h = 0; 
while ($h < 24) { 
    $key = date('H:i', strtotime(date('Y-m-d') . ' + ' . $h . ' hours')); 
    $value = date('h:i A', strtotime(date('Y-m-d') . ' + ' . $h . ' hours')); 
    $formatter[$key] = $value; 
    $h++; 
} 

結果是：

Array 
(
    [00:00] => 12:00 AM 
    [01:00] => 01:00 AM 
    [02:00] => 02:00 AM 
    [03:00] => 03:00 AM 
    [04:00] => 04:00 AM 
    [05:00] => 05:00 AM 
    [06:00] => 06:00 AM 
    [07:00] => 07:00 AM 
    [08:00] => 08:00 AM 
    [09:00] => 09:00 AM 
    [10:00] => 10:00 AM 
    [11:00] => 11:00 AM 
    [12:00] => 12:00 PM 
    [13:00] => 01:00 PM 
    [14:00] => 02:00 PM 
    [15:00] => 03:00 PM 
    [16:00] => 04:00 PM 
    [17:00] => 05:00 PM 
    [18:00] => 06:00 PM 
    [19:00] => 07:00 PM 
    [20:00] => 08:00 PM 
    [21:00] => 09:00 PM 
    [22:00] => 10:00 PM 
    [23:00] => 11:00 PM 
) 

Answer 6

這裏有一個更靈活的版本，不需要日期時間（因爲我們已經與時間戳以秒爲工作反正）。 ;-)

function get_hours_range($start = 0, $end = 86400, $step = 3600, $format = 'g:i a') { 
     $times = array(); 
     foreach (range($start, $end, $step) as $timestamp) { 
       $hour_mins = gmdate('H:i', $timestamp); 
       if (! empty($format)) 
         $times[$hour_mins] = gmdate($format, $timestamp); 
       else $times[$hour_mins] = $hour_mins; 
     } 
     return $times; 
} 

Answer 7

這裏是我的建議：

$start = new \DateTime('00:00'); 
    $times = 24 * 2; // 24 hours * 30 mins in an hour 

    for ($i = 0; $i < $times-1; $i++) { 
     $result[] = $start->add(new \DateInterval('PT30M'))->format('H:i A'); 
    } 

    print_r($result); 

希望這有助於。
