That doesn't address the fact that your directory, stemming from
$_SERVER['DOCUMENT_ROOT'], could be "/var/www/html/blah/foo" or
"C:\Program Files\Apache Group\Apache\htdocs\blah\foo". Which is why I
will want to delete all of one type of file from a directory, the issue
lies in the fact that I am wanting to use command-line calls to remove
them all at one time (which honestly I thought was a time saver, but
honestly, is that slower or faster than your suggestion of opendir() -
readdir() while loop? I would think the while loop is slower as it has
to loop where a command-line remove command would be faster, but that's
just me), by using the * wildcard I cannot encase the path structure in
double-quotes, but in Windows, my directory from the doc root might
have spaces in it:
c:\Program Files\Apache Group\Apache\htdocs\My Directory\blah\foo
Why anyone would do that would be beyond me, but it is viable to occur
of course.
Also, for some strange reason, whenever I do this, it fails in spite of
the fact that $_SERVER['DOCUMENT_ROOT'] contains the path from the root
to the docroot:
[PHP]
list($removeKommand, $removeRedirect) =
@array_values($dbAP->getKommandOSArray('rmdir')); // GETS EITHER
WINDOWS OR NON-WINDOWS REMOVE COMMANDS AND REDIRECTION
$msg = exec("$removeKommand \"" . actual_path($_SERVER['DOCUMENT_ROOT']
.. '/blah/foo') . "/*.zip*\" $removeRedirect");
[/PHP]
