Php 为什么Json_encode返回空数组？

以下是我正在使用的json：

{
    "data": [{
        "Contact_Name": {
            "id": "1884053000034678068"

            },

            }]
        }, {
            "product": {
                "id": "1884053000030235273"
            },
            "Product_Name": Printed Dress - Color: Orange,

            }]
        }, {
            "product": {
                "id": "1884053000012868763"
            },

            "Discount_Amount": 0,
            "line_tax": [{
                "percentage": 20,
                "name": "TVA"
            }]
        }],
        "Adjustment": 0,

        "Quantite_totale": 3
    }],
    "duplicate_check_fields": ["ID_Lip"],
    "trigger": []
}

但是，当我使用json_encode（）函数时，它不会返回一个对象json，而只是返回一个空数组，而且我在代码中也没有看到任何语法错误。我不知道这是真的语法错误还是别的什么。。有人能帮我知道问题出在哪里吗？ 提前谢谢你

解决方案 改用

json\u解码（$jsondata，true）

详细说明：

要使用的Propper JSON 您的json字符串中还有一个错误

以下是要使用的propper json：

为了未来 检查json以获得安全的结果

我希望这有帮助

您的json在“产品名称”附近的语法中有错误

价值观​​必须是字符串，因此介于“”之间

如果您有解决问题，请告诉我们：）

祝你有愉快的一天

这已经是

编码的

数据，因此请使用

json\u decode（）

将其转换为数组问题中的json不是有效的json，它有几个语法错误。请尝试使用确定错误欢迎使用堆栈溢出！请拿着（你得到了一个徽章！），四处看看，仔细阅读，特别是我还推荐乔恩·斯基特的。我们无法帮助您处理无法看到的代码。请用一个（注意“最小值”）来更新这个问题，它演示了这个问题。我确实纠正了错误，它是有效的！
