Need to edit this opendir script

<php>

Code (markup):

I want this code to display content of some other directory instead of home directory where the file is stored. Can you help me out.

 

$files = getFiles("./");

PHP:

... you have to specify the path to the directory in this line.

 

The script worked fine. I edited the extension by mistake which created errors. Thanks for telling.

 

Show me the path you've used.

 

Also can I display only files with some specific extension. ie files with .exe or .mp3 .
