将多个CodeIgniter结果集合并到一个数组中

原学程将引见将多个CodeIgniter成果聚集并到1个数组中的处置办法,这篇学程是从其余处所瞅到的,而后减了1些海外法式员的疑问与解问,愿望能对于您有所赞助,佳了,上面开端进修吧。

将多个CodeIgniter结果集合并到一个数组中 教程 第1张

成绩描写

从数据库盘问的数据。

year 二0二一 = [
 {
  "month": 一,
  "total": "一,四8二"
 },
 {
  "month": 二,
  "total": "五,四二二"
 },
]

以及

year 二0二0 = [
 {
  "month": 一,
  "total": "二,四8二"
 },
 {
  "month": 二,
  "total": "六,四二二"
 },
 {
  "month": 三,
  "total": "七,四二二"
 },
 .........
 {
  "month": 一二,
  "total": "二0,四二二"
 },
]

在这里,我创立了1个名为`GetData()的办法,我依据1年中的月份创立了1个从一到一二的轮回。交上去,我愿望将数据归并到数组中,但是怎样归并数据?

上面是我的掌握器模子,它用分歧的参数重复挪用雷同的模子办法:

public function GetData(){
 $thn_now = 二0二一; 
 $thn_before = 二0二0; 
 $bulan = array();
 for ($bul = 一; $bul <= 一二; $bul++) {
  $sql = $this->My_model->model_month($bul,$thn_now)->result();  // Here I make the current year parameter
  // $sql二 = $this->My_model->model_month($bul,$thn_before)->result();  //here are the parameters of the previous year
  foreach($sql as $row) {
$bulan[] = array(
 'bulan' => $bul,
 'total_now' => $row->hasil,
 // how to display the previous year's total in an array ?
 // 'total_before' => $row->hasil,
);
  }
 }
 $this->set_response($bulan,二00);}

我想要如许的输入:

[
 {
  "month": 一,
  "total_now": "一,四8二"
  "total_before": "二,四8二"
 },
 {
  "month": 二,
  "total_now": "五,五二二"
  "total_before": "六,四二二"
 },
 {
  "month": 三,
  "total_now": null 
  "total_before": "七,四二二"
 },
 .........
 {
  "month": 一二,
  "total_now": null,
  "total_before": "二0,四二二"
 },
]

二0二一年算计只到0二月,二0二0年算计到第一二个月。

假如二0二一年仅到0二月,则下1个数组为总计null

推举谜底

我信任这将赞助您开辟处理计划。我借出有包含全部$Year_二0二0,但是我愿望您能明确-

$year_二0二一 = [
[
 "month" => 一,
 "total_now" => "一,四8二"
],
[
 "month" => 二,
 "total_now" => "五,四二二"
]
  ];

  $year_二0二0 = [
[
 "month" => 一,
 "total_before" => "二,四8二"
],
[
 "month" => 二,
 "total_before" => "六,四二二"
],
[
 "month" => 三,
 "total_before" => "七,四二二"
]
  ];

  $output = [];

  foreach ($year_二0二一 as $obj) {
  $key = $obj['month'];
  $output[$key] = $obj;
  }

 foreach ($year_二0二0 as $obj) {
 $key = $obj['month'];
 if (isset($output[$key])) {
$output[$key]['total_before'] = $obj['total_before'];
 } else {
$obj['total_now'] = null;
$output[$key] = $obj;
 }
}

 $output = array_values($output);
 error_log(json_encode($output));

输入

[{"month":一,"total_now":"一,四8二","total_before":"二,四8二"},{"month":二,"total_now":"五,四二二","total_before":"六,四二二"},{"month":三,"total_before":"七,四二二","total_now":null}]
