如何从php中的curl get请求中提取“ SALECODE”和“ PRICE”以供以后的MySql比较并插入（如果不同），结果是什么类型的JSON？

?php

$url = 'http://everywhere.smartcash.ro/everywhere/rest/TSmartCashMethods/GetArticleInfo/4/1/1/1/';

$cURL = curl_init();

curl_setopt($cURL, CURLOPT_URL, $url); curl_setopt($cURL, CURLOPT_HTTPGET, true);

curl_setopt($cURL, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Accept: application/json' ));

$result = curl_exec($cURL);

curl_close($cURL);



//print_r($result);

$json = json_decode($result, true); print_r($json);



echo $json["SALECODE"];


?>

样品响应：

Answer 1

尝试改用$json['result'][0]['DATASET'][0]['SALECODE']。

如果您仔细查看响应数据，您会发现它是高度嵌套的。 result也是一个数组，因此您需要从中选择一项。在这种情况下，只有一个。如果还有其他内容，则需要遍历$json['result']。

Answer 2

<?php

$url = 'http://everywhere.smartcash.ro/everywhere/rest/TSmartCashMethods/GetArticleInfo/4/1/1/1/';

$cURL = curl_init();
curl_setopt($cURL, CURLOPT_URL, $url);
curl_setopt($cURL, CURLOPT_HTTPGET, true);
curl_setopt($cURL, CURLOPT_RETURNTRANSFER, true);
curl_setopt($cURL, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Accept: application/json' ));
$result = curl_exec($cURL);
curl_close($cURL);


$json = json_decode($result, true);

echo "Price: " . $json['result'][0]['DATASET'][0]['PRICE'];
echo "<hr>";
echo "Sales code: " . $json['result'][0]['DATASET'][0]['SALECODE'];

?>

Answer 3

您的json看起来像这样。

您需要执行以下操作： $ json ['result'] [0] ['DATASET'] [0] ['SALECODE'];

JSON是什么类型？如何用php解析？
