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