I've tried many variations and different methos posted around here and in the php manaul and none of them seem to work.
Windows XP (WAMP 5)
$command = "\"C:\Program Files\FLAC\metaflac.exe\" --show-md5sum $file";
exec($command, $output, $rv);
where $file is things like:
D:\Lossless\2pac\Loyal To The Game [2004][02] The Uppercut [EDI & Noble Of Outlawz].flac
D:\Lossless\2pac\Loyal To The Game [2004][03] Out On Bail.flac
What's wrong with that?
