Ciao.
C'è qualcuno che mi spiega perchè se si
mette delle lettere accentate questo esempio
non funziona (funziona solo con FILTER_SANITIZE_STRING)
mentre in tutti gli esempi nel web è consigliato
l'uso di FILTER_SANITIZE_STRING,FILTER_FLAG_ENCODE_HIGH|FIL TER_FLAG_ENCODE_LOW
Esempio provare per credere

$name = filter_input(INPUT_POST, 'uno',FILTER_SANITIZE_STRING,FILTER_FLAG_ENCODE_HIGH|FILTER_FLAG_ENCODE_LOW);

$name = filter_input(INPUT_POST, 'uno',FILTER_SANITIZE_STRING,FILTER_FLAG_STRIP_LOW|FILTER_FLAG_STRIP_HIGH);
