Permission of /tmp/ files

Can you guys suggest a way to change the permission of the files created in /tmp/ via PHP sessions?

I'm trying to access the session files from Perl, but PHP creates the files with permission 0600 by default (user "nobody"). The permission of the /tmp/ directory is set to 1777.

FWIW, my site is the only one on the server, so there's no concern of other accounts accessing the files.

 

rebuild_phpconf --current:

Available handlers: dso cgi none
DEFAULT PHP: 5
PHP4 SAPI: none
PHP5 SAPI: dso
SUEXEC: enabled


umask:
0022

That second "0" was a surprise; I expected it to just return 022.

 

On my end, it looks like Perl is running as Group, so it doesn't have the ability to change the permission. Security isn't a major issue; I have a dedicated server with only one site on it (mine), so there's no concern of another account picking up data from the same directory.

Would this work?

session_start();

$sess_file = "/tmp/sess_" . session_id();

if (!$_SESSION['whatever']) {
// Only change permission of new sessions
if (is_file($sess_file)) {
chmod($sess_file, 0644);

chown($sess_file, "myaccount");
chgrp($sess_file, "myaccount");
}

$_SESSION['whatever'] = "whatever";
}


In running this, changing the permission worked, but chown and chgrp gave an error that the "operation is not permitted".

 

For my purposes, in order to share PHP sessions with Perl, it looks like I don't need to change the owner and group; all I needed was to change the permission. So, this worked fine:

session_start();
$sess_file = "/tmp/sess_" . session_id();

if (!$_SESSION['whatever']) {
if (is_file($sess_file)) chmod($sess_file, 0644);

$_SESSION['whatever'] = "whatever";
}


I can then access it in Perl using PHP::Session.

If anyone knows of a better way, please feel free to post it! Ideally, I would be able to modify PHP itself to create all files as 0644. But for now, this workaround seems to work.
