fwrite - chmod

[arfa]

A standard file write routine - generating the file $fname on the first run.
[code=php:0]
$fh = fopen($fname, 'w');
fwrite($fh,$data);
fclose($fh);
[/code]
On the current server the file, $fname, is written with permission and status:
-rw-r--r--  www-data
So... trying to later write to the file doesn't work.
Being www-data it resists standard fTP chmod command.
It also fails:
chmod("$fname", 0666);

Any suggestions or comments here would be most welcome.

thanks

what error do you get when trying to write to the file the second time?

try to use this [code]fopen("/home/rasmus/file.gif", "wb");[/code]

thanks for the replies.

A bit more testing and it seems we are writing.
The problem still remains with chmoding -
via my FTP prog - error message= Operation not permitted. May not be supported on remote site. Or,

via PHP using: chmod("$fname", 0666);

ooops, hit the post button....

rasmus/file.gif", "wb");
I am definitely not on a win server (but should get into the 'portability' habit)

via my PHP chmod script using: chmod("$fname", 0666);
I was getting:
Warning: chmod() [function.chmod]: Operation not permitted in /home/ftp/.../....../..
but now see that this is only for directories.

This thread is a bit of a space waster - other than forcing me to write out my process, and examine the various steps and presumptions along the way - AND learn as a result.
sorry about that
thanks for your tolerance
