mkdir problem

Hi all I posted a message yesterday regarding mkdir giving a permission denied error message when trying to create a directory in my web space. I only received one message from someone who also had the problem. I need to be able to mkdir using php rather than doing it manually through ftp. Has anyone got any ideas on why php isn't letting me create a directory. I'm using the following mkdir("/home/site/web/temp", 0700); php returns a false and a permission denied error message. the server is using php 4.0.1.pl2 as an apache module on a linux server. I'd appreciate any suggestions anyone can give me to fix this problem. oh, I'm having the same problem on two other linux redhat based systems also. -- Regards Nick nallan@wdev.net
