PHP检测输入的时间戳范围是否大于一天

Question

我有一个日期选择器表单，可以选择两个范围之间的日期。当按下提交按钮时，它会调用一个查询来获取这两个日期之间的数据。我想要做的是，如果他们选择一个大于 24 小时的日期范围，它将只显示每天的总计，而不是他们选择的每一天的每一天的每个数据。我现在拥有的表格具有时间戳格式 yyyy-dd-mm hh-mm-ss。我如何使用 PHP 检测到这一点？

示例表

    Date                  Count 
    2016-04-23 06:26:11     75
    2016-04-23 07:30:12     90
    2016-04-24 12:26:11     100
    2016-04-24 06:27:14     200
    2016-04-25 08:16:19     102
    2016-04-26 13:10:07     300

示例代码

$link=Connection();

$data1 = '2016-04-23 06:26:11';
$data2 = '2016-04-23 06:30:11';
//if(isset($_POST['range1']) && $_POST['range2']){
//$data1 = $_POST['range1'];
//$data2 = $_POST['range2'];

$dteStart = new DateTime($data1);
$dteEnd = new DateTime($data2);
$dteDiff = $dteStart->diff($dteEnd);
echo $dteDiff->format('%a'); 

//Display one day of values
if($dteDiff == 0){
    $result = mysql_query(
                      "
                      SELECT DISTINCT Date, Count
                      FROM testLocation 
                      WHERE Date 
                      BETWEEN '$data1%' AND '$data2%'
                      "
                      ,$link
                      );        
}
//Sum each day for the month
else if($dteDiff > 0 && $dteDiff < 30){
    $result = mysql_query(
                          "
                          SELECT DISTINCT Date, Count
                          FROM testLocation 
                          WHERE Date 
                          BETWEEN '$data1%' AND '$data2%'
                          "
                          ,$link
                          );
}
//Sum each month for the year
else if($dteDiff > 30){
    $result = mysql_query(
                          "
                          SELECT DISTINCT Date, Count
                          FROM testLocation 
                          WHERE Date 
                          BETWEEN '$data1%' AND '$data2%'
                          "
                          ,$link
                          );
};

Answer 1

这是你可以做的

SELECT Date, SUM(Count)
      FROM testLocation 
      WHERE Date 
      BETWEEN '$data1%' AND '$data2%' GROUP BY date(Date)

或

SELECT Date, SUM(Count)
      FROM testLocation 
      WHERE Date 
      BETWEEN '$data1%' AND '$data2%' GROUP BY DATE_FORMAT(Date, '%Y-%m-%d')

已更新

SELECT DATE(Date) as dategroup, SUM(Count)
  FROM testLocation 
  WHERE Date 
  BETWEEN '$data1%' AND '$data2%' GROUP BY DATE(Date)
