chmod problems...

[Ask Josephsen]

Hi NG

If I write the following:

<?php
$file="myfile.JPG";
if ( getmyuid()==fileowner ( $file ) )
{
chgrp ( $file, getmygid() );
chown ( $file, getmyuid() );
chmod ( $file, 0600 );
}
?>

And the result is this:

Warning: chgrp(): Operation not permitted in /.../test/index.php on line
5
Warning: chown(): Operation not permitted in /.../test/index.php on line
6
Warning: chmod(): Operation not permitted in /.../test/index.php on line
7

Does that mean the functions (chgrp, chown, chmod) has been disabled on my
php-deamon? I assume; if I own the file I should be able to change the
rights of the file? It is possible to do this by ftp, but I'd rather do it
by the php-script.
Thanks....

Try to change your error-reporting value to E_ALL, and look if there is
some more information.
Also look in phpinfo() for disabled functions.

Hi again

My "disable_functions" in the php-core is set to "no value | no value"
(found in phpinfo()). The "Configure Command" is the following:

Configure Command './configure' '--prefix=/usr' '--libdir=/usr/lib'
'--enable-shared' '--disable-static' '--disable-debug' '--disable-rpath'
'--enable-pic' '--enable-inline-optimization' '--with-config-file-path=/etc'
'--enable-magic-quotes' '--enable-debugger' '--enable-track-vars'
'--with-exec-dir=/usr/bin' '--with-versioning' '--with-mod_charset'
'--with-expat-dir=/usr' '--with-regex=php' '--enable-force-cgi-redirect'
'--enable-track-vars' '--enable-trans-sid' '--enable-safe-mode'
'--with-ctype' '--with-ttf' '--with-freetype-dir=/usr' '--with-zlib'
'--enable-sysvsem' '--enable-sysvshm' '--enable-yp' '--enable-ftp'
'--with-gettext' '--without-aspell' '--without-kerberos'

Changing the level of error reporting did not make any change (I placed
"error_reporting(E_ALL);" and "ini_set('error_reporting', E_ALL);" at the
top of the script).

I still get:

Warning: chgrp(): Operation not permitted in /.../test/index.php on line
5
Warning: chown(): Operation not permitted in /.../test/index.php on line
6
Warning: chmod(): Operation not permitted in /.../test/index.php on line
7

From the manual for chown ()...
Note: This function will not work on remote files as the file to be
examined must be accessible via the servers filesystem.

Note: When safe mode is enabled, PHP checks whether the files or
directories you are about to operate on have the same UID (owner) as the
script that is being executed.

Does this help ?

Hi

Unfortunately not, the files are placed locally and the current dir is both
owned by the same user id and the permissions are 0777 (read/write/execute
for all).

Thanks though...

The following User and Group must be the same on your file as they are
in your httpd.conf file.
User www
Group staff

It also depends on your OS and how it is setup.
For example, you may not be able to change the owner of the file unless
you are root user.

Have you tried changing these permissions from the command line, logged
in as the same user that you webserver is running from?

I hope you are not running this on a external web server.

Hi

It is the userpermissions on the server - the php-user is missing the
"write" permissions.

Thanks for your time....
