Question

我想解析JSON字符串，以便将其保存为二维数组，如下所示。只有我带来的解决方案包括3个或4个foreach循环，我不认为这很好。

 {
  "root": {
    "row": [
      {
        "Status": "Enabled",
        "Keyword": "Toaletna voda",
        "Campaign": "Lešenari",
        "Adgroup": "Lešenaris",
        "BidStrategyType": "InheritFromParent",
        "Bid": "0.05",
        "Matchtype": "Broad",
        "Clicks": "0",
        "Impr.": "0",
        "Conv.": "0"
      },
      {
        "Status": "Enabled",
        "Keyword": "lyžička",
        "Campaign": "Lešenari",
        "Adgroup": "Lešenaris",
        "BidStrategyType": "InheritFromParent",
        "Bid": "0.05",
        "Matchtype": "Broad",
        "Clicks": "0",
        "Impr.": "0",
        "Conv.": "0"
      },
      {
        "Status": "Search total",
        "Keyword": "-",
        "Campaign": "-",
        "Adgroup": "-",
        "BidStrategyType": "-",
        "Bid": "-",
        "Matchtype": "-",
        "Clicks": "0",
        "Impr.": "0",
        "Conv.": "0"
      },
      {
        "Status": "Content total",
        "Keyword": "-",
        "Campaign": "-",
        "Adgroup": "-",
        "BidStrategyType": "-",
        "Bid": "-",
        "Matchtype": "-",
        "Clicks": "0",
        "Impr.": "0",
        "Conv.": "0"
      },
      {
        "Status": "Deleted items total",
        "Keyword": "-",
        "Campaign": "-",
        "Adgroup": "-",
        "BidStrategyType": "-",
        "Bid": "-",
        "Matchtype": "-",
        "Clicks": "0",
        "Impr.": "0",
        "Conv.": "0"
      },
      {
        "Status": "Overall total",
        "Keyword": "-",
        "Campaign": "-",
        "Adgroup": "-",
        "BidStrategyType": "-",
        "Bid": "-",
        "Matchtype": "-",
        "Clicks": "0",
        "Impr.": "0",
        "Conv.": "0"
      }
    ]
  }
}

它应该返回类似这样的东西

Keyword=>Toaletna voda
Keyword=>lyžička
Campaign=>Lešenari
Campaign=>Lešenari
Adgroup=>Lešenaris
Adgroup=>Lešenaris
Bid=>0.05
Bid=>0.05
Clicks=>0
Clicks=>0
Impr.=>0
Impr.=>0
Conv.=>0
Conv.=>0

它应该与此函数做同样的事情，它接受名称数组，并在该xml文件中找到附加到它的值

public function LoadXmlReport($adSystemColumns = array())
    {
        require "config.php";

        $xmlfile = simplexml_load_file(dirname(__FILE__) . "/xmlfile.xml");
        foreach ($xmlfile as $key => $value)
            foreach ($value as $columnName => $item) {
                if ($item == "-") {
                    break;
                } elseif (array_search($columnName, $bing) !== FALSE)
                    $this->report[$columnName][] = $item;
            }

        foreach ($this->report as $key => $value)
            foreach ($value as $index => $item)
                echo $key."=>".$item."<br/>";
    }

这些是值

$bing = array(
"Adgroup",
"Campaign",
"Keyword",
"Clicks",
"Impr.",
"Conv.",
"Bid",
"Adgroup"
);

Answer 1

$json = json_decode($jsonString, true);
$result = [];
array_walk_recursive($json, function ($value, $key) use (&$result) {
    $result[$key][] = $value;
});

将json字符串解析为数组
