php - 用于 Json 输出的 php 数组

Question

我正在尝试获得最佳实践来操作我的数组以获取格式类似于此格式的 json(更好地使用图表)

   {
    "serieMonth":["Aug-12","Sep-12","Oct-12","Nov-12","Dec-12","Jan-13","Feb-13"],
    "serieCA":[4214,10119,13325,12818,7177,20628,7664],
    "serieAdwordsCA":[0,0,0,0,0,310,332],
    "serieBooking":[10,28,46,34,17,51,16],
    "serieAdwords":[0,0,0,0,0,1,1],
    "serieTotalBooking":[10,28,46,34,17,52,17],
    "serieCartRepartition":[421,361,290,377,422,397,451],
    "serieTotalCart":[421,361,290,377,422,397,451]
    }

实际上我的输出是这样的:

[
{"date_year":"2012","date_month":"08","ad_cost":"0.0","ad_clicks":"0"},
{"date_year":"2012","date_month":"09","ad_cost":"0.0","ad_clicks":"0"},
{"date_year":"2012","date_month":"10","ad_cost":"0.0","ad_clicks":"0"},
{"date_year":"2012","date_month":"11","ad_cost":"0.0","ad_clicks":"0"},
{"date_year":"2012","date_month":"12","ad_cost":"44.9","ad_clicks":"43"},
{"date_year":"2013","date_month":"01","ad_cost":"297.56","ad_clicks":"462"},
{"date_year":"2013","date_month":"02","ad_cost":"82.5","ad_clicks":"103"}
]

我正在使用 javascript 来更改它:

var xAxisLabels = new Array(),
adClicks = new Array(),
adCost = new Array();
$.each(data, function(i,v) {
  xAxisLabels.push(v["date_month"]+'/'+v["date_year"]);
  adCost.push(parseInt(v["ad_cost"]));
  adClicks.push(parseInt(v["ad_clicks"]));
});

我正在寻找在 php 中执行此操作的最佳方法，因为我通过 google api 获取了这些数据，这是我的 php。

// dimensions
$dimensions = 'ga:year,ga:month';
$_params[] = 'date_year';
$_params[] = 'date_month';
// metrics
$metrics = 'ga:adCost,ga:adClicks';
$_params[] = 'ad_cost';
$_params[] = 'ad_clicks';

$response = $service->data_ga->get('ga:' . $projectId, $from, $to, $metrics, array('dimensions' => $dimensions));

$analyticsStats = array();
foreach ($response['rows'] as $row) {
  $dataRow = array();
  foreach ($_params as $colNr => $column) {
    $dataRow[$column] = $row[$colNr];
  }
  array_push($analyticsStats, $dataRow);
}

您可以构建一个数组数组，然后在循环中将项目添加到子数组中:

$output = array(
    "serieMonth" => array(),
    "serieCA" => array(),
    "serieAdwordsCA" => array(),
    "serieBooking" => array(),
    "serieAdwords" => array(),
    "serieTotalBooking" => array(),
    "serieCartRepartition" => array(),
    "serieTotalCart" => array()
);
foreach($response["rows"] as $row) {
    $output["serieMonth"][] = date("Y-M", strtotime("{$row['date_year']}-{$row['date_month']}-01"));
    $output["serieCA"][] = $row["ad_cost"];
    $output["serieAdwordsCA"][] = $row["ad_clicks"];
    // etc...
}
echo json_encode($output);
