정의되지 않은 변수 오류

Question

안녕하세요 저는 Denis이고 저는 PHP를 처음 사용합니다. 우리 아빠는 PHP 개발자이지만 혼자서하고 싶습니다. 나는 11 살이야! :)

나는 내 PHP는 일에 대한 설치 프로그램을 만들어이 오류 얻을 : 그것은 실패를이 부분의

Notice: Undefined variable: config in \path\to\core.php on line 20 

:

$system['home_url'] = "".$config['home']['url'].""; 

을하지만이 포함 된 경우 어떻게 실패 할 수 있습니다 config 파일을 앞에두고이 변수는 정의되지 않았습니다!

은 내가 그랬어 : require('config.php');

config.php 파일의 코드는 다음과 같습니다

$config['home']['url'] = "http://localhost/"; 

것은 내가 변수를 잘 사용하고 있는가? 나는 모든 인터넷을 검색했고 단지 global을 사용하여 솔루션을 찾았지만 어떻게 작동하는지 실제로 알지 못합니다 ..

안녕! 사용 사장님 isset($config['home']['url']) 전에 감사 :)))
