codrgii Posted May 29, 2011 Share Posted May 29, 2011 Using the preg_replace function, how can i enable the use of Latin a-b letters alongwith basic english a-z and without jeopardising security? just to be clear i would like to only allow Latin a-b characters and english a-z removing anything else if anyone is unsure what Latin a-b characters are then goto http://en.wikipedia.org/wiki/List_of_Unicode_characters Quote Link to comment https://forums.phpfreaks.com/topic/237736-filtering/ Share on other sites More sharing options...

wildteen88 Posted May 29, 2011 Share Posted May 29, 2011 You mean something like this $str = '$#La souri$<<>-//s a été mangée par le chat '; $str = preg_replace('/[^\p{L}\s-]/u', '', $str); echo $str; //Outputs La souri-s a été mangée par le chat This is not my code.
