Note Submitter: no-michael-spam at placecreativecompany dot com ---- You can't rely on is_dir() and a permissions check to know whether opendir() will succeed. I'm working on a Windows system and accessing files on an OSX share. There are file/folder names with unsupported characters in them, (such as ">"), so opendir() fails with "the volume label syntax is incorrect." However, is_dir() will report - correctly - that it these are valid directories! Though for what it's worth, Windows can't get in there either. The ">" character existing in the folder name is a problem for both. Bottom line: you may need to test the result of opendir() before you go on to process it, even if you've checked permissions and is_dir() beforehand.
