Question

我无法访问通过curl返回的数据。数据作为复杂字符串返回。我说复杂，因为它使用花括号，它看起来像一个数组。

我尝试像访问数组一样访问数据，例如。 $var['key']，但这给了我一个错误： WARNING: Illegal string offset

以下是通过curl返回的内容：

string(1422) "{"transactions":
[{"transaction_id":143720,"currency_adjustment":20,"offer_id":null,"offer_name":null,"description":"Cash Out","timestamp":"11\/19\/14"},
{"transaction_id":143718,"currency_adjustment":-10,"offer_id":null,"offer_name":null,"description":"Cash Out","timestamp":"11\/19\/14"},
{"transaction_id":143716,"currency_adjustment":-10,"offer_id":null,"offer_name":null,"description":"Cash Out","timestamp":"11\/19\/14"},
{"transaction_id":143672,"currency_adjustment":0.1,"offer_id":null,"offer_name":null,"description":"Referral Earnings","timestamp":"11\/19\/14"}]}"

我希望获得currency_adjustment的访问权限。

我试着这样做：

$response['currency_adjustment']＆amp; {$response['currency_adjustment']}

如何访问此字符串中的数据？

Answer 1

只是这样做：

$array = json_decode($your_string);

Answer 2

$result = (array)json_decode($response);
$data  = $result["transactions"];
echo $data[0]["currency_adjustment"];
