PHP. How to remove a %0D character from my code
问题
我正在尝试通过每日摘要的方式向自己发送一封包含一些RSS源的电子邮件。我收到了以下错误消息，由于多余的%0D字符导致的。您能建议我在代码中需要进行哪些更改以删除它吗？
非常感谢
错误信息为：simplexml_load_file(https://hdblog.it/feed%0D)：无法打开流：无效的重定向URL！

你现在是否在运行Windows？
％0D是回车符。您正在使用\n（换行符）拆分输入文件，但也许您的输入文件具有\r\n行终止符。尝试改为使用'\r\n'进行拆分。
如果您的输入文件是在与您运行代码的平台上创建的，您可以尝试使用php常量PHP_EOL。
英文:
Are you running on Windows?
%0D is the carriage return character. You are exploding the input file on \n (line feed), but perhaps your input file has \r\n line terminators. Try exploding on '\r\n' instead.
If your input file has been created on the same platform as you are running your code you could try using the php constant PHP_EOL.
