Question

我有下面的JSON数据，并且想使用php打印“ Page”和“ PageCount”，让我知道我该怎么做。

{
    "response": {
        "Page": 1,
        "PageCount": 1,
        "RecordsSent": 1,
        "RecordsFound": 1,
        "Stock": [
            {
                "Colour": "OFF WHITE",
                "Size": "S",
                "Style": "A0000001",
                "Article": "FLORAL 1",
                "Size_Range": "S - 3XL",
                "In_Stock": 58,
                "Demand": 0,
                "Supply": 2,
                "Sell_Price9": 0
            }
        ]
    }
}

我如何仅打印“页面”和“ PageCount”？

Answer 1

您可以解析它，如下所示：Live Demo

<?php

 $json = '{
           "response": {
             "Page": 1,
             "PageCount": 1,
             "RecordsSent": 1,
             "RecordsFound": 1,
             "Stock": [
                       {
                        "Colour": "OFF WHITE",
                        "Size": "S",
                        "Style": "A0000001",
                        "Article": "FLORAL 1",
                        "Size_Range": "S - 3XL",
                        "In_Stock": 58,
                        "Demand": 0,
                        "Supply": 2,
                        "Sell_Price9": 0
                       }
                      ]
           }

          }';

$decoded_json = json_decode($json);

echo "Page: ".$decoded_json->response->Page."<br/>";
echo "Page Count: ".$decoded_json->response->PageCount;

Answer 2

您可以尝试以下代码：

$content = '{
    "response": {
        "Page": 1,
        "PageCount": 1,
        "RecordsSent": 1,
        "RecordsFound": 1,
        "Stock": [
            {
                "Colour": "OFF WHITE",
                "Size": "S",
                "Style": "A0000001",
                "Article": "FLORAL 1",
                "Size_Range": "S - 3XL",
                "In_Stock": 58,
                "Demand": 0,
                "Supply": 2,
                "Sell_Price9": 0
            }
        ]
    }
}';
$data = json_decode($content, true);

echo "Page:", $data['response']['Page'], "\n";
echo "PageCount:", $data['response']['PageCount'];

json_decode第二个参数是

Assoc-为TRUE时，返回的对象将转换为关联数组。

这意味着，如果assoc = false或不被设置，则表明您拥有对象：

echo "Page:", $data->response->Page, "\n";
echo "PageCount:", $data->response->PageCount;
