can I unlink the same file that is being executed?

can I unlink the same file that is being executed? using the unlink() function, if I am running test.php, can I have unlink('test.php'); in the test.php file? also, do I need to have proper file permissions for the file to be able to unlink? what perms should I use? chmod 777?

Also, when I try unlinking a file, it fails? Why? I already chmod to 777.

You should be able to - the PHP parser reads the file, parses it, and then actually runs the commands. I would think that the file would be closed by the time the commands were actually run. I'll try this on my server, and see what happens.

It works fine for me. I tested it on an Apache server running on my home computer, which is running Windows XP. If your server is running a Unix-based OS, then there might be problems with the file permissions.

Yep, as I suggested with the file perms.. any ideas? I played around, but no luck

Maybe your server is running safe mode. This will sometimes stop you from performing operations on files if they don't have the same UID as the PHP interpreter. If you don't know whether safe mode is on, try doing phpinfo().
