我从一个客户端继承了一个项目，该项目使用 JSON 和 PHP 来显示来自在线房地产服务的房地产列表。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。其他时候数据会加载，但在显示一些属性后不会转换。过渡由 jQuery 循环插件控制。

我已经包含了下面的所有代码。非常感谢任何帮助。

谢谢你。

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

如果你有一个旧版本的 PHP 缺少你可以在upgrade.phpjson_decode()中找到一个兼容的
