아래 코드를 사용하면 매우 강력 해 보입니다. 다른 언어 (UTF-8)로 작동하고 이제 결과를 데이터베이스에 저장하려고합니다. 내 문제는 내가 오래되고 구형 인 mysql 문에 익숙하고 mysqli를 사용하고 싶다는 것이다. 누구든지 입력을 받아 데이터베이스에 저장하는 간단하면서도 안전한 기능을 가르쳐 주시겠습니까? 그리고이 코드에서이 코드를 어디에 추가해야하는지 알려주십시오.암호화 된 텍스트를 저장하는 mysqli 함수
<?php
/*
* PHP 5.3.18 on windows XP
*
* I don't have open_ssl active from PHP so used MCRYPT_RAND for the salt.
* It is adequate for this exercise.
*
* As the encoded SALT and encrypted output are binary code i have converted all
* the output to Base64 encoding to ensure it is HTML safe.
*
* It selects the appropriate default action in the 'do' select list.
*
* There is a new 'salt' generated at each encryption and the user is prevented from
* changing it by making the display field as 'readonly'. Normally this would be a 'hidden' field'.
