apache listing directory contents
 

if i go to http://mysite.com/folder

then apache is listing all the files in 'folder'. i'm sure this must be a php ini setting or some similar. how do I change it? it would probably be useful to know that i don't have access to the apache conf file as it's on a shared hosting server.

If the server is configured to allow the use of .htaccess, you can create a file .htaccess containing:
and upload it to the folder you want to hide it's contents.
Else create and upload an empty index.html (or index.php) file to that folder.
