PHP file creation problem - ownership

Hi, I've come across an odd problem which I've never had before. I've got a domain, with multiple subdomains. everything going OK with all my FOPEN / FWRITE commands. Now, I've started a new subdomain, and come across a situation where the PHP script "owner" is different from the owner of the subdirectory, and I cannot write to that folder. $log.="USER '".get_current_user()."'\n"; As I said I've never had this prob before & my other scripts do not bother with checking/changing ownership. I've Googled and can see how to change the owner of an EXISTING file. However, how do you change the owner of a file yet to be created - so it's the same as the file structure and allow upload? PS I am the *ONLY* FTP user for this account/website. -- Gordon.
