PHP scandir returns incorrect filenames

Question

scandir(some path) is giving incorrect filenames.

When I do a ls of the folder, I get results like

selected0_LjRNXtMpXn4_0:0:0.mp4      selected8054_YdZl86snmag_0:2:32.mp4
selected10_iJTkxI6WMbo_0:2:20.mp4    selected8056_jgABBaXQSK8_0:3:40.mp4

However, scandir is returning the following:

S4XFWK~B.MP4
SDTP6P~D.MP4
SHTYF1~M.MP4
SX8WCA~J.MP4

I have double and triple checked to make sure that I am ls -ing and scandir -ing the same folder. Why is scandir not returning correct filenames?

Update: Machine running scandir is a windows server 2008 enterprise, machine the files are stored on is running fedora 20, with disk type fuse.glusterfs

Answer 1

Found the answer. The filenames when viewed from a linux system had a colon : in them, which isn't a valid windows filename, so they were replaced with the 8.3 names.
