All the other solutions are creepy because they are from someone that arrogantly simply thinks that English is the only language in the world     All those solutions strip also diacritics like    or      The perfect solution  as stated in PHP documentation  is simply    clear   strip tags  des

You can do it in one single line    specially useful for GET or POST requests   clear   preg replace     A-Za-z0-9 -         urldecode   GET  id

to allow periods and any other character just add them like so   change      a-zA-Z     to     a-zA-Z
