About fopen() for write and PHP settings

First of all I apology for my poor use of English of my newbish(?) questions because I didn't find any solutions the first time I e-mailed this list. What my problem is: I am on a server that has these configurations like these: http://kainga.quasarnet.org/php.php . Let's say my username is user1 and server files' owner is httpd . I have a script in my public html dir that tries to fopen("./somefile.txt", "w") [note: is_writable for this file returns false but its permissions are rw-rw-r--) but it always fails. However, when the servers' owner changed the somefile.txt's owner to httpd the script could write to it without any problem. Is there any way that I can make the script write to somefile.txt without changing its owner to httpd (I even changed the file's permissions to rwx-rwx-rwx and it still wouldn't let the script write to it)? I really need help with this and I hope it can be solved easily. PS. Whatever I did PHP would return false on is_writable, which returned true when the file's owner changed to httpd. Thank you in advance, Arty2
