Recursively read subdirectory, check names of subdirectories in mysql db, if not exist: delete directory

[DanH]

Hello everybody :)

To finish my little project i would like to make a cleaner.php script.
I will call it via cron and want it to check 1 main directory for
subdirectories.
I only care about the 1st level subdirectories and their names. When i
delete a directory i want to delete the directory, all its
subdirectories (if there are any) and all its files.

Step 1:
Read in all the subdirectories from the main directory.

Step 2:
When the subdirectories in the main directory are known, i want to
check if these names are known in the database.

Step 3:
If they are known in the database; do nothing.
If they are not known in the database; delete the directories that are
not known in the database (and their subs/contents).

Can anyone help me with this please? Please give me some hints.

If any freelancers find this a nice script to code for a reasonable
price let me know too ;)

thanx!
Dan

This iterator class might help:

Delete the directories with rmdir() (there are a number of folks who
have posted recursive directory removal scripts on this page ...that is
if you don't use the iterator class to build your own):

I assume you know how to check against the database.
