note 100389 added to function.htmlentities

Special thanks to all those whose comments, concerns, and contributions went into this code, as well as all those on this site. You will need the arrays I posted in my earlier note: $HTML_ENTS, $HTML_TAGS, and $Xchars <?php /* encode to XHTML for instructions, fully commented sourcecode, and test example, see: http://softmoon-webware.com/php_functions-instructions.php/ http://softmoon-webware.com/php_functions.zip/ // this will encode all 'stray' (X)HTML entites as needed // without effecting 'valid' existing markup.
