I believe when PHP saves a file, it is already owned by the web server user.
In my case, nouser. I could not get this behaviour to change.
Normally you should not need to CHMOD or CHOWN anything you upload unless
you need them to be modified by ftp users as well.
Just make sure the folder is writeable by the web server user. (Preferably
not by anybody else... 777 is all bad :)
If you do end up CHMODing:
On SCO, the CHMOD command did not behave like I expected it to... adding the
umask made it all good... ie,
$rand_name=generate_filename("","jpg")
//Save The Uploaded File To Disk
@copy($image,
"/home/sites/madden.williamsen.net/web/recruiter/resumes/$rand_name") or
die("Couldn't Save File $image to $rand_name");
(Note beginning slash... Robert helped you there :)
//Give It Perms
umask(0);
chmod("/home/sites/madden.williamsen.net/web/recruiter/resumes/$temp_name",0
600);
(on my SCO box, 600 is the default perms anyway )
Here is my little funtion I use to generate file names: (It is not mine..
but I cant remember who gave it to me :)
function generate_filename ($len = 8,$ext)
{
$nps = "";
mt_srand ((double) microtime() * 1000000);
while (strlen($nps)<$len)
{
$c = chr(mt_rand (0,255));
if (eregi("^[a-z0-9]$", $c)) $nps = $nps.$c;
}
$nps.=".$ext";
return ($nps);
}
Of course, depending on what you are doing, completely random names may be
useless... I save them as temporary files to resize them and save them in a
DB with the regular name with special chars stripped out.

You could replace the file name with a randomly generated number. There are
a number of ways to generate random numbers in PHP. Try this for starters:

You need the path from root to the directory. Now you have:
"home/sites/madden.williamsen.net/web/recruiter/resumes/$img1_name"
You need a forward slash before home:
"/home/sites/madden.williamsen.net/web/recruiter/resumes/$img1_name"
Instead of using chmod 777 (ick!) you should change the ownership of the
file to be owned by the web server user which is usually "nobody" you can do
this with the chown command from the command line.
