'download'클릭하면 0.9.2라고 된 압축파일 다운.

압축풀어서 다른거는 다 버리고 그냥 RSS.php 파일만
원하는 위치에 놓으시고요~ (/home/RSS.php)

newschannel.txt 을 저장 (/home/newschannel.txt)


news_rss.php을 저장 (/home/news_rss.php)

토탈3개의파일 :
/home/RSS.php
/home/newschannel.txt
/home/news_rss.php

여기서 news_rss.php 파일을 여셔서..
16번째줄, 26번째줄 에 있는 파일 경로를 수정

[RSS.php 파일 경로 - 수정전]
require_once "RSS.php";
[수정후]
require_once $DOCUMENT_ROOT."/RSS.php";

[RSS.php 파일 경로 - 수정전]
$fd = fopen ($"newschannel.txt", "r");
[수정후]
[RSS.php 파일 경로 - 수정전]
$fd = fopen ($DOCUMENT_ROOT."/newschannel.txt", "r");

그리고는 주소창에서 news_rss.php 를 불러옴
