How to Effectively Remove HTML Special Character Codes Beyond strip_tags?

Effective HTML Special Character Removal: Extending Beyond strip_tags

While strip_tags effectively removes HTML tags, it might leave behind HTML special character codes. These codes, such as ' ' and '©', can disrupt your RSS feed file content.

To address this issue, consider utilizing one of these functions:

1. html_entity_decode: Decodes these codes into their corresponding characters.
2. preg_replace: Utilizes regular expressions to remove the codes using the following pattern:

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

This pattern matches and removes any character code with a semicolon.

Refined Approach

To limit the potential for unintended replacements, adjust the regular expression as suggested by Jacco:

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

This revised pattern only matches and removes codes with a length of 2 to 8 characters to avoid accidentally modifying complete sentences.
