Question

我的数组的var_dump：

   array(10) { ["idcomment"]=> string(2) "26" [0]=> string(2) "26" ["parentcomment_id"]=> string(2) "25" [1]=> string(2) "25" ["comment"]=> string(531) "damnJoin Dev Center and publish your app in the Windows Phone Store.

["dt"]=> string(19) "2013-04-29 21:36:29" [3]=> string(19) "2013-04-29 21:36:29" ["iduser"]=> string(1) "1" [4]=> string(1) "1" }

结果为json_encode($comment)：

{"idcomment":"26","0":"26","parentcomment_id":"25","1":"25","comment":null,"2":null,"dt":"2013-04-29 21:36:29","3":"2013-04-29 21:36:29","iduser":"1","4":"1"}

我遗漏了comment字段。它适用于较短的字符串......我做错了什么？

Answer 1

您的评论部分中有一个引号首先使用str_replace将其转义为

$newstring =str_replace('\'', '\\\'', $myString);

然后执行json_encode

json_encode($newstring, true);

Answer 2

最有可能的是，您的字符串未使用json_encode期望的UTF-8进行正确编码。有关详细信息，请参阅UTF-8 all the way through。

如果您使用其他编码（例如 Windows-1252）编码现有数据，请使用mb_convert_encoding之类的函数在JSON编码之前将其转换为UTF-8。 / p>
