最近24小时的数据报告显示。 如果一个小时内未创建报告,则默认为零。
我的查询
$dayReport = Report::select(DB::raw("HOUR(created_at) as hourNo,SUM(site_id) as count"))
->where('site_id',$site->id)
->whereDate('created_at','>=', \Carbon\Carbon::now()->subHours(24))
->orderBy("created_at")
->groupBy(DB::raw("hour(created_at)"))
->get()
->toArray();
输出如下:
data: [0,2,4,2,2,0,0,0,0,0,0,0,0,0,0,5,6,7,0,8,0,6,10,22]
我的输出是:
data: [2,4,2,2]
这是Javascript 0中的Chart Js数据,默认值在1小时内未报告创建。
先谢谢您...

从查询中,您将获得小时和总计。..您可以尝试以下代码
$results = array(array('hour' => 2, 'count' => 3), array('hour' => 3, 'count' => 3), array('hour' => 13, 'count' => 10));
$hours = array(1,2,3,4,5,6,7,8,9,10,11,12,13); //up to 24
$finalResult = [];
foreach($hours as $hour){
$hourSearch = array_search($hour, array_column($results, 'hour'));
if(is_numeric($hourSearch)) {
// array_push($finalResult, $results[$hourSearch]);
array_push($finalResult,$results[$hourSearch]['count']);
} else {
// $data['hour'] = $hour;
// $data['count'] = 0;
//array_push($finalResult, $data);
array_push($finalResult,0);
}
}
echo json_encode($finalResult);

我已经阅读了 @Shibon 的答案,它看起来不错
我在根据以下情况创建图表时遇到相同的情况 https://github.com/ConsoleTVs/Charts
所以我为此创建了函数
这里是仅包含值的数组,但我需要将其他值设置为零,以便创建自己的函数
$arrayWithValues =
[
'02' => '20',
'09' => '45',
'15' => '68',
'21' => '28'
];
$defaultEmptyArray = [
'00' => '0',
'01' => '0',
'02' => '0',
'03' => '0',
'04' => '0',
'05' => '0',
'06' => '0',
'07' => '0',
'08' => '0',
'09' => '0',
'10' => '0',
'11' => '0',
'12' => '0',
'13' => '0',
'14' => '0',
'15' => '0',
'16' => '0',
'17' => '0',
'18' => '0',
'19' => '0',
'20' => '0',
'21' => '0',
'22' => '0',
'23' => '0',
];
现在我们只需要替换具有该值的数组,而我已经编写了自己的函数
function setUnsettedArray($actulHourWithValue = [] ,$defaultEmptyArray = [])
{
$arraNotExists = [];
foreach ($defaultEmptyArray as $defKey => $defValue)
{
if (array_key_exists($defKey, $actulHourWithValue))
{
$arrayEXists[] = [$defKey => $actulHourWithValue[$defKey]];
}
elseif (!array_key_exists($defKey, $actulHourWithValue))
{
$arraNotExists[] = [$defKey => $defValue];
}
}
$newArray = array_merge($arraNotExists,$arrayEXists);
foreach ($newArray as $newKey => $newValue)
{
$keys[] = $newKey;
foreach ($newValue as $key => $value)
{
$allKesy[] = $key;
$allValues[] = $value;
}
}
$finalArray = array_combine($allKesy,$allValues);
ksort($finalArray);
return $finalArray;
}
并尝试将数组作为print_r(setUnsettedArray($arrayWithValues,$defaultEmptyArray));
这是小提琴
http://phpfiddle.org/main/code/sfq3-adyn
我已经编辑了setUnsettedArray
函数
function setUnsettedArray(array $arrayWithValues ,array $defaultArray)
{
$finalArray = $arrayWithValues+$defaultArray;
ksort($finalArray);
return $finalArray;
}
我已经看过您的查询,但查询结果不佳
所以试试这个
$lastTwentyFour = Report::where('site_id','=',$site->id)
->whereDate('created_at', '=', Carbon::now()->subHours(24))
->orderBy('created_at')
->get()
->groupBy(function($date)
{
return Carbon::parse($date->created_at)->format('H');
}
);
您可以将每小时的收集数计为
foreach ($lastTwentyFour as $newGroupByKey => $newGroupByValue)
{
$eachHour[] = $newGroupByKey;
$eachHourCount[] = $newGroupByValue->count();
}
$actulHourWithValue = array_combine($eachHour,$eachHourCount);

我似乎不太了解您的问题,但是使用碳元素在处理日期时会很有帮助,它将使您的代码减少很多行。 `$ now = Carbon \ Carbon :: now; $ hoursBefore = $ now-> subDays(1);
$ reports = Report :: where('site_id',$ site-> id)-> whereBetween('created_at',[$ hoursBefore,$ now])-> get()-> toArray(); `
我希望这会有所帮助。 谢谢,祝您好运,并祝您编程愉快。...:)
