PHP 함수 복수 반환

Question

이것은 알프레드 워크 플로를위한 것입니다. 내 첫 번째거야.

나는 여러 개의 반환 값을 가진 함수를 만들고 있습니다. 각 함수에서 배열을 만들고 인덱스 페이지의 연관 배열을 통해 반환 값에 액세스하려고하므로 여러 값을 가진 배열을 반환해야합니다. 이 작업을 수행하는 더 좋은 방법이 있습니까? 내가 제대로하고 있니? 출력 할 수없는 것 같습니다.

    // Checks to see if the settings file exists and is valid 
    $check = check_settings($settings_file);

사용 쉼표 대신 배열 선언 세미콜론. 더 낮은 버전의 PHP와 호환되도록 array() 구문을 사용해야합니다.

$output = array(

    // Read the settings file into an associative array so that we can use it. 
    'settings' => json_decode(file_get_contents($settings_file) , TRUE), // <- Commas not semicolons 

    // grab the username 
    'username' => $settings['username'], // <- Commas not semicolons 

    // grab and decrypt the password 
    'password' => decrypt_string($settings['password']) 
);
