Ch0cu3r Posted February 18, 2014 Share Posted February 18, 2014 (edited) htmlentitites should be htmlentities ( entities spelt with two t's not three) Edited February 18, 2014 by Ch0cu3r Quote Link to comment Share on other sites More sharing options...

AbraCadaver Posted February 18, 2014 Share Posted February 18, 2014 This will never strips tags: $var = htmlentities($var); $var = strip_tags($var); Maybe reverse them. Quote Link to comment Share on other sites More sharing options...
