File deletion and privilages

Can somebody please help?

I am using php to create a subdirectory on my hosting server using the command : mkdir($webpath,0777);

I then copy files into that subdir.

However, when I later try and delete the files and the subdir using my FTP software I get an insufficient privilages error.

How come? I now have a server full of subdirectories and files which I cannot delete.

Any help would be much appreciated.

you need to make sure that when you chmod you allow everyone to read, write and run from the directories

i also have some i cant delete and i created them in FTP. Anyone help?

Sorted now - thanks.
