分区阵列分成多个阵列，由小时

Question

我有一个PHP阵列是这样的： Pastebin Array Exemple

每个数组元素具有TIME键。我想用小时分割这个数组。

实施例：

• 8H之间用键TIME每个阵列元素 - 8h59 = 1个阵列

• 9h之间用键TIME每个阵列元素 - 9h59 = 1个阵列

• 每个具有密钥TIME在10h - 10h59 = 1之间的数组元素

• ETC ...

而这一天的所有时间。

请帮我解决这个问题。

编辑：

现在我有这个是工作，但我想有一些简单得多。

$sales_by_hours = array(); 
    foreach($sales_array as $element){ 

     $time = strtotime($element['TIME']); 
     if ($time >= strtotime('7:00') && $time <= strtotime('7:59')){ 
      $sales_by_hours['7:00'][] = $element; 
     } 
     if ($time >= strtotime('8:00') && $time <= strtotime('8:59')){ 
      $sales_by_hours['8:00'][] = $element; 
     } 
     if ($time >= strtotime('9:00') && $time <= strtotime('9:59')){ 
      $sales_by_hours['9:00'][] = $element; 
     } 
     if ($time >= strtotime('10:00') && $time <= strtotime('10:59')){ 
      $sales_by_hours['10:00'][] = $element; 
     } 
     if ($time >= strtotime('11:00') && $time <= strtotime('11:59')){ 
      $sales_by_hours['11:00'][] = $element; 
     } 
     if ($time >= strtotime('12:00') && $time <= strtotime('12:59')){ 
      $sales_by_hours['12:00'][] = $element; 
     } 
     if ($time >= strtotime('13:00') && $time <= strtotime('13:59')){ 
      $sales_by_hours['13:00'][] = $element; 
     } 

    }

简单比你有什么是

$sales_by_hours = array(); 
foreach($sales_array as $element) { 
    // the H is 24-hour format of an hour with leading zeros - 00 through 23 
    $key = date('H:00', $time); 

    // make sure the key exists in the array 
    if(!isset($sales_by_hours[$key])) { 
     $sales_by_hours[$key] = array(); 
    } 

    $sales_by_hours[$key][] = $element; 
}
