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:
- html_entity_decode: Decodes these codes into their corresponding characters.
- 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.
