  • PHP에서 prepare()와 bind_param() 사용예제 　
    <?php// 데이터베이스 연결 정보$servername = "localhost";$username = "your_username";$password = "your_password";$dbname = "your_database";// 데이터베이스 연결$conn = new mysqli($servername, $username, $password, $dbname);// 연결 확인if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error);}// 입력받을 이름과 나이$name = "홍길동"; // 예시 데이터$age = 30; // 예시 데이터// SQL 쿼리 템플릿 준비 (Prepare Statement)$sql = "INSERT INTO users (name, age) VALUES (?, ?)";$stmt = $conn->prepare($sql);// prepare() 실패 시 오류 처리if (!$stmt) { die("Prepare failed: " . $conn->error);}// 파라미터 바인딩 (Bind Parameters)// 'si'는 순서대로 name은 string, age는 integer임을 나타냅니다.$stmt->bind_param("si", $name, $age);// 쿼리 실행 (Execute Statement)if ($stmt->execute()) { echo "새로운 레코드가 성공적으로 입력되었습니다.";} else { echo "레코드 삽입 실패: " . $stmt->error;}// Statement 종료$stmt->close();// 데이터베이스 연결 종료$conn->close();?>bind_param() 메서드: 역할: prepare()로 준비된 SQL 쿼리 템플릿의 플레이스홀더에 실제 데이터를 바인딩합니다. 동작 방식: 첫 번째 인수로 바인딩할 파라미터의 데이터 타입을 나타내는 문자열을 받습니다. i: integer (정수) d: double (실수) s: string (문자열) b: blob (바이너리 데이터) 이후 인수로 바인딩할 실제 변수의 참조를 순서대로 전달합니다. bind_param()은 전달된 데이터를 SQL 쿼리에 직접 삽입하는 대신, 데이터베이스 서버에 안전하게 전달하여 플레이스홀더를 대체합니다. 이렇게 하면 SQL Injection 공격을 효과적으로 방지할 수 있습니다. 반환 값: 성공 시 true, 실패 시 false를 반환합니다.
