Tim,

What's in your PHP error log?  It's always the first place I check when 
I have weird problems.

Have you checked the contents of $file?  Is it correct - including the 
path?  What is the result of filesize($file)?  What are the ownership 
and permissions on the file?  Does the web server have read access to it?
