How to remove html special chars?

I am creating a RSS feed file for my application in which I want to remove HTML tags, which is done by strip_tags. But strip_tags is not removing HTML special code chars: 

  & ©

etc.

Please tell me any function which I can use to remove these special code chars from my string.

Solution

  • Either decode them using html_entity_decode or remove them using preg_replace:

    $Content = preg_replace("/&#?[a-z0-9]+;/i","",$Content);

    (From here)

    EDIT: Alternative according to Jacco's comment

    might be nice to replace the '+' with {2,8} or something. This will limit the chance of replacing entire sentences when an unencoded '&' is present.

    $Content = preg_replace("/&#?[a-z0-9]{2,8};/i","",$Content);
