我非常接近让这个解析器/图像工作，但我有一些最终问题阻止我发布它。更糟糕的是，我完全不知道问题可能是什么。
以下是整个代码：

这是一个让查找线更容易的pastebin。此外，出于故障排除目的而显示为已删除的任何行都应视为正常的未注释行。我只是将它们注释掉以使故障排除更容易一些。
现在，它的工作方式是有三个 $_GET 变量，分别称为u、t和w。如果设置了前两个变量，则第一个 if 语句通过。如果设置了第二个和第三个变量，则第二个 if 语句通过。在这两种情况下，解析器只是获取数据，并将其存储在 .json 文件中，所以它看起来像这样（其中第一个数字是用户 ID）：
{"601869":{"userName":"hiigaran","userTeamRank":"33","userOverallRank":"6,923","userPoints":"8,297,436","userPPD":"10,656","date":"2014-04-19 20:53:00"}}
现在首先，我收到很多这样的警告：
Warning: DOMDocument::loadHTML(): Unexpected end tag : b in Entity, line: 280 in D:\xampp\htdocs\sigimage.php on line 8
但是，我认为我可以忽略它们，因为它们对我来说不是问题，也不是解析或保存数据的障碍。但是，我还有很多其他问题。第一次使用时，我有空的 .json 文件，这些是我通过第一个 if 语句时收到的消息：
Warning: fread(): Length parameter must be greater than 0 in D:\xampp\htdocs\sigimage.php on line 99
Warning: fread(): Length parameter must be greater than 0 in D:\xampp\htdocs\sigimage.php on line 18

或者如果它通过了第二个 if 语句：

Warning: fread(): Length parameter must be greater than 0 in D:\xampp\htdocs\sigimage.php on line 64

如果 .json 文件中已有数据，我只会收到 DOMDocument 警告。但是，图像仍然没有显示，它只是给了我关于它如何由于错误而无法显示的消息。
这听起来可能有很多要问的问题，但我已经走了这么远，感觉就像我在这里想念的那样简单。
让我更困惑的是我的第一个版本运行良好。我正在开发的第二个版本旨在扩展功能以显示由用户确定的第二件事的统计信息，所以我在这里不知所措。如果有帮助，这是第一个版本的代码。
