Question

我有以下数组：

["entity_id"] => "1"
["customer_id"] => "18"
["public_hash"] => "xxxxxxxxxx041e6f5246f041429424422795137118223d73bb6197410f9cbc77"
["payment_method_code"] => "braintree"
["type"] => "card"
["created_at"] => "2018-12-19 21:24:13"
["expires_at" => "2020-06-01 00:00:00" "gateway_token"] => "8cx9y7"
["details"] => "{"type":"AE","maskedCC":"0005","expirationDate":"05\\\\\\\\/2020"}"
["is_active"] => "1"
["is_visible"] => "1"

我正试图分别从["details"]获取值（类型，maskedCC，expirationDate）

使用 $ details = $ card-> getData（'details'）; 我可以将其范围缩小到：

{"type":"AE","maskedCC":"0005","expirationDate":"05\/2020"}

从那里，我不确定如何获取值AE，0005、05 / 2020。

Answer 1

您正在处理jsonObj。您必须先将其解码为数组。 $ key将是您想要获得的属性（类型，maskedCC，expirationDate）

$jsonArray = json_decode($details,true);
echo $jsonArray[$key];

Answer 2

由于它是一个字符串，并且看起来是有效的JSON，因此您可以对其进行解码：


$details = json_decode($card->getData('details'), true);

if (!empty($details))
{
    //Valid JSON
    echo $details['type'];
    echo $details['maskedCC'];
    echo $details['expirationDate'];
}
else
{
    echo 'The details string was not valid JSON.';
}
