I noticed that when I
foreach (glob (
etc.
I get a warning: "Invalid argument supplied for foreach()". This is obviously not fatal
and the code will work, but for a testing server it's irritating having to sift through
meaningless warnings (it's also irritating if you end up with warnings reported on a production
server, ug). My quick and dirty solution:
foreach (($result_set = glob ("????") ? $result_set : array ("empty_filename"))
as $filename)
{
if ($filename = "empty_filename")
echo "No four-letter file";
}
Hope this helps someone that's as irritated as I was.
