Replace unwanted characters

Sometimes you might want to generate a filename out of a real persons name. In that situation a '/' character can really do a lot of harm. But there are more characters that might not do well in a filename.

The following snippet replaces characters with friendly characters.

$unwanted_array = array(
  '\' => '_', ' ' => '_', '/' => '_', ',' => '_',
  'Š'=>'S', 'š'=>'s', 'Ž'=>'Z', 'ž'=>'z', 'À'=>'A', 'Á'=>'A', 'Â'=>'A', 
  'Ã'=>'A', 'Ä'=>'A', 'Å'=>'A', 'Æ'=>'A', 'Ç'=>'C', 'È'=>'E', 'É'=>'E',
  'Ê'=>'E', 'Ë'=>'E', 'Ì'=>'I', 'Í'=>'I', 'Î'=>'I', 'Ï'=>'I', 'Ñ'=>'N',
  'Ò'=>'O', 'Ó'=>'O', 'Ô'=>'O', 'Õ'=>'O', 'Ö'=>'O', 'Ø'=>'O', 'Ù'=>'U',
  'Ú'=>'U', 'Û'=>'U', 'Ü'=>'U', 'Ý'=>'Y', 'Þ'=>'B', 'ß'=>'ss', 'à'=>'a',
  'á'=>'a', 'â'=>'a', 'ã'=>'a', 'ä'=>'a', 'å'=>'a', 'æ'=>'a', 'ç'=>'c',
  'è'=>'e', 'é'=>'e', 'ê'=>'e', 'ë'=>'e', 'ì'=>'i', 'í'=>'i', 'î'=>'i', 
  'ï'=>'i', 'ð'=>'o', 'ñ'=>'n', 'ò'=>'o', 'ó'=>'o', 'ô'=>'o', 'õ'=>'o',
  'ö'=>'o', 'ø'=>'o', 'ù'=>'u', 'ú'=>'u', 'û'=>'u', 'ý'=>'y', 'þ'=>'b', 
  'ÿ'=>'y', 'Ğ'=>'G', 'İ'=>'I', 'Ş'=>'S', 'ğ'=>'g', 'ı'=>'i', 'ş'=>'s', 
  'ü'=>'u', 'ă'=>'a', 'Ă'=>'A', 'ș'=>'s', 'Ș'=>'S', 'ț'=>'t', 'Ț'=>'T'
);

$name = strtr( $name, $unwanted_array );
