目录结构
chatroom文件下有source文件夹、conf文件夹、userlist.php等
source文件夹下有SqlHelper.class.php、userlistController.php
conf文件夹下有dbconf.xml.
其他文件忽略。
现在问题是当userlist.php不在source文件夹下时会出现如下提示。(放在source文件夹下正常》
Warning: DOMDocument::load() [function.DOMDocument-load]: I/O warning : failed to load external entity "file:///C%3A/wamp/www/test/ajax/chatroomtest/conf/dbconf.xml" in C:\wamp\www\test\ajax\chatroomtest\chatroom\source\SqlHelper.class.php on line 14
Fatal error: Call to a member function getElementsByTagName() on a non-object in C:\wamp\www\test\ajax\chatroomtest\chatroom\source\SqlHelper.class.php on line 19
