Question

我从客户端继承了一个项目，该项目使用JSON和PHP从在线房地产服务中显示房地产物业列表。服务提供的数据会加载，但与它们关联的属性和代理会混淆。有时会显示所有属性，但只有一个代理与之关联。其他时候数据加载，但在显示一些属性后不会转换。转换由jQuery循环插件控制。

我已经包含了以下所有代码。非常感谢任何帮助。

谢谢。

在尝试调试decode_json_string()函数之前，您应该尝试PHP的内置json_decode() http://php.net/manual/en/function.json-decode.php

如果您的旧版PHP缺少json_decode()，则可以在upgrade.php

中找到兼容的版本
