Question

我目前正在与Sophos UTM合作，将无线统计信息推送到另一个平台，并尝试提取这种数据格式。
它结构清晰，看起来像面向类的JSON，但无法完全弄清它是什么或如何将其转换为可用的东西。有任何想法吗？我曾想过只用PHP编写JSON转换器，但恐怕我可能只是想念一块拼图。

您的样本数据在通往有效json镇的路上要进行4次维修。

进行以下替换：

=>至:
'至"
删除所有结尾的,，后跟零个或多个空格字符，然后删除一个]
将您的undef值括在双引号中

代码：（Demo）

$almostjson = <<<ALMOSTJSON
...your input string
ALMOSTJSON;
$json = preg_replace(["~=>~", "~'~", "~,(?=\s*])~", "~:\s+\Kundef~"], [':', '"', '', '"$0"'], $almostjson);
var_export(json_decode($json, true));

在包含键-值关系的字符串上调用正则表达式函数很容易导致意外匹配。在可以改善数据源之前，应将此“解决方案”视为“临时”。如果字符串中的文本质量错误，则此解决方案将来可能会无提示地失败。
