Question

我从Webhook收到一些JSON POST数据到我的服务器。我可以按如下方式获取JSON数据：

$orderJSON = file_get_contents('php://input');

返回此JSON：

我现在需要从JSON获取单个元素，例如我想得到id值（3304）。我试过了：

$orderID = $orderJSON->id;

和

 $orderID = $orderJSON[id];

但这只会产生错误，例如＆＃39;尝试获取非对象的属性＆＃39;。

Answer 1

您需要先使用json_decode()，因为我无法在您的问题中看到这一点。
id位于order家长之下，因此您需要像$orderJSON->order->id
您还必须检查已解码的$orderJSON是否为空

实施例

$orderJSON = json_decode($orderJSON);
if (empty($orderJSON)) {
    throw new RuntimeException('Malformed json');
}
$orderID = $orderJSON->order->id;

Answer 2

使用json_decode()函数将JSON文件转换为PHP可读数据。

<?php
$json = json_decode($orderJSON);

解码完JSON文件后，可以使用函数print_r()打印数据的精确表示。

<?php
print_r($orderJSON);

这可以帮助您确定文件的形成方式，从而确定显示所需值所需的所有尺寸。

JSON to nice

现在，如果仔细观察，您会发现为了打印您的ID，您需要通过订单维度。

因此，您可能希望使用语法$json->order->id来定位所需的ID。

<?php
echo $json->order->id;

Display the ID from JSON

PHP : JSON

PHP : print_r()
