json编码数据库字符串值的问题

Question

我在php数组中有数据库查询结果如下：

Array
(
    [status] => 1
    [message] => Successfully Login
    [request] => Array
        (
            [firstName] => Jugni
            [lastName] => Patel
            [popup_message] => To login to this portal you have to agree out terms and condition
• L80 – R169 pm x 24 on SMARTCHAT 1GB
• G3 Beat – R259 pm x 24 on SMARTCHAT 1GB
• G3 – R399 pm x 24 on SMARTCHAT 1GB
Top 5 MTN Sales consultants for period 2-8 March 2015, on G3 & G3 Beat sales will WIN R500 each! You have until Monday 9 March 9AM to log your sales for this competition!
        )

)

当我在做上面数组的json_encode时，它在描述中给出了空值。

{"status":"1","message":"Successfully Login","request":{"firstName":"Jugni","lastName":"Patel","popup_message":null}}

更新

现在我可以使用utf8_encode方法获取描述的值。 但是当我再次使用json_decode对该字符串进行解码时，它会给出以下输出：

它给出如下解码值：

stdClass Object
(
    [status] => 1
    [message] => Successfully Login
    [request] => stdClass Object
        (
            [firstName] => Jugni
            [lastName] => Patel
            [popup_message] => To login to this portal you have to agree out terms and condition
• L80 – R169 pm x 24 on SMARTCHAT 1GB
• G3 Beat – R259 pm x 24 on SMARTCHAT 1GB
• G3 – R399 pm x 24 on SMARTCHAT 1GB
Top 5 MTN Sales consultants for period 2-8 March 2015, on G3 & G3 Beat sales will WIN R500 each! You have until Monday 9 March 9AM to log your sales for this competition!
        )

)

有谁知道如何在json_encode之后获得相同的描述字段值？

Answer 1

请确保数组中的字符串为utf8 - 已编码。 json_encode需要utf8 - 已编码的字符串，并且会在faliure上返回false。
