PHP의 기본 질문

Question

로그온하려고하면 인증되지 않습니다. 오류가 반환되지 않습니다. 사용자 이름과 암호가 코드에 있습니다 (사용자 이름과 암호는 데이터베이스에 보관되지 않은 PHP 코드 안에 있습니다).

elseif($auth_status == 0); { 
echo '<h4>Authentication error please try again! </h4>' . "\n\n";

Answer 1

주의 사항 :

이 내 코드입니다.이 0이면 ; (아무 작업도하지 않음)을 실행합니다. 다음과 같이 작성하려고했을 수 있습니다.

if ($auth_status) { 
    echo '<h3>Welcome Back, Betty!</h3>'; 
} else { // or elseif (!$auth_status) { // <-- no semi-colon 
    echo '<h4>Authentication error please try again! </h4>' . "\n\n"; 
}
