Does anyone have experience in getting unlink to work within the context
of a cron?

I created my own garbage collection function and I am trying to delete
some session files through a cron that runs every 10 minutes.

The session files are owned by 'www'
The cron is ran by 'actsmin'

The 'unlink' command works within the context of a php script when
activated by a user on the web site.
Is there another file deletion command within PHP other than unlink?

Here is the error message I am e-mailed by the cron when it doesn't
successfully delete a session file:

Warning: unlink(/path/to/sessions/files/): Is a directory in /path/to/php/script/cron/calls/script.php on line 47

That has nothing to do with whether this is running from cron or not.

unlink is to remove files, rmdir is used to remove directories.

Since /path/to/sessions/files/ is a directory, you can't use unlink to remove it.

Please read the documentation, it's quite clear for these functions.
