This function uses the power of regexp to check if some bad word are on the text, also offers the posibility to change those word for something else. Examples:\r\n\r\n$texto = \'fuck off!\';\r\nfiltrado($texto); returns true since a bad word has been found on the text\r\nfiltrado($texto, \'[censored]\'); //returns [censored] off!\r\n\r\nAnd because regexp, this will work with something like \"fck off!\".
