질문 Q #22827
foreach 문을 2번 사용
황현빈 2020-10-29 13:55:18

ci 2로 개발하고 있습니다.

 

모델에서 db의 테이블을 조회해서 컨트롤러에서 $data['list']에 담고 뷰로 $data를 넘겨주었습니다.

 

뷰에서 foreach 문으로 $list를 돌면서 테이블에 출력했습니다.

정상적으로 출력이 되었는데 같은 뷰 페이지에서 한번더 foreach문으로 $list의 값을 다시 출력하니 읽지를 못하네요

 

foreach문에서 변수를 한번 사용하면 변수가 사라지는 건가요?

 

재 사용하려면 어떻게 해야되나요?

$list를 var_dump를 찍었을때 array(100)이 출력되고 foreach문이 끝나고 다시 var_dump를 찍으니 object(stdClass)#43 이렇게 출력되네요

소스코드가 어떻게 되어있나요?

소스 어딘가에서 재선언했을겁니다.

2번째줄에..

foreach(array_reverse($list) as $key => $list) {

라고 되어있네요.
