Is there a silver bullet function in PHP that will clean a string so it's suitable for RSS?

Question

I have a lot of data that contains characters that will normally break RSS. Is there a function or library in PHP that will handle these characters so they are suitable to be printed in an RSS Feed?

Answer 1

RSS is simply XML. So the characters escaped by htmlspecialchars() should be sufficient or htmlentities() escapes some extra characters, which might be useful.

Answer 2

http://php.net/manual/en/function.htmlentities.php

Take a look at the comments, there are some xmlentities functions there you can use (since RSS is XML).

Answer 3

Use htmlentities() and it will encode the strange character in a strange encoding but it wouldn't break RSS.
