PHP - mkdir with wrong owner

Question

I have an simple PHP script that creates a folder and then copies certain files into it. The folder (and copied files) have all 755 permissions. The problem is, it sets the user as Apache. Now I can not delete or change permissions through FTP. I can only 'reset ownership' in my DirectAdmin. There I can see the user changes from "Apache" to "matthdc58".

How can I let PHP create a folder with "matthdc58" as user? I tried chown() - failed:

Warning: chown() [function.chown]: Operation not permitted in /home/matthdc58/domains/hiddendomain.com/public_html/Home.php on line 78

Warning: chown() [function.chown]: Operation not permitted in /home/matthdc58/domains/hiddendomain.com/public_html/Home.php on line 79

Warning: chown() [function.chown]: Operation not permitted in /home/matthdc58/domains/hiddendomain.com/public_html/Home.php on line 80

Warning: Cannot modify header information - headers already sent by (output started at /home/matthdc58/domains/hiddendomain.com/public_html/Home.php:78) in /home/matthdc58/domains/hiddendomain.com/public_html/Home.php on line 90

I also tried (seemed to solve others' problems) php_flag safe_mode off in my .htaccess, to no prevail.

My whole PHP script:

$dirtocreate = 'userdata/'.$_SESSION['uname'];
$oldumask = umask(0); 
mkdir($dirtocreate, 0755);
umask($oldumask);

copy('img/100x100.png', $dirtocreate.'/100x100.png');   
copy('img/64x64.png', $dirtocreate.'/64x64.png');   

//Verify correct owner
chown($dirtocreate, 'matthdc58');
chown($dirtocreate.'/100x100.png', 'matthdc58');
chown($dirtocreate.'/64x64.png', 'matthdc58');

//Verify correct permissions, just to be sure               
chmod($dirtocreate,0755);
chmod($dirtocreate.'/100x100.png',0755);        
chmod($dirtocreate.'/64x64.png',0755);

So, just to clarify:

• My PHP script sets the owner of the new folder to "Apache".
• The PHP script fails to change the owner to "matthdc58".
• Now, I can not edit the folder through FTP, since the owner is "Apache".
• I can only restore ownership through DirectAdmin with the "Restore Ownership" button.

Answer 1

Please check you have chmodded and chowned your directory: /home/matthdc58/domains/hiddendomain.com/public_html/ to your username. :)

Answer 2

It turned out to be related to the version of PHP I was using.
At recommendation of my host, Versio, I changed the version of PHP by adding

<FilesMatch "\.php$">
AddHandler x-httpd-php54 .php
</FilesMatch>

to my .htaccess file.

I don't think this is relevant for others, as this had to do with the rights, but you can always try.
Again, thanks to @LeSamAdmin for helping me out!
