mkdir does not work?

Unable to create dir

[iProgram]

I use Plesk and there is a website in /var/www/vhosts/mysite.com/httpdocs directory. I uploaded a script to the httpdocs folder and I can access it via URL mysite.com/mkdir.php:

>cat mkdir.php
<?
if(mkdir('/var/www/vhosts/mysite.com/test/abc'))
echo "TRUE";
else
echo "FALSE";
?>

As you can see in my source code, I want to create a directory in /var/www/vhosts/mysite.com/test/ directory. The mode of test directory is 777. But I always receive FALSE. I tried to create a dir in httpdocs/a_tmp_777_dir and it works. Why I couldn't create dir outside the httpdocs directory?

It is usually a matter of rights and safe mode.

If your server is running php in safe mode, then you can only alter directories that you own.

The doc for mkdir() says:

 Note: When safe mode is enabled, PHP checks whether the directory in which you are about to operate has the same UID (owner) as the script that is being executed.

[iProgram]

According to phpinfo(), the safe_mode is Off.

The user of php script is apache. So I even changed the ownership of /var/www/vhosts/mysite.com/test directory into apache. But it still doesn't work.

Try this:

<?
if(mkdir('test/abc')) {
echo "TRUE";
 } else {
echo "FALSE";
}
?> 

Also, make sure that 'test' exists.

This works because it creates dir in httpdocs directory. My problem is unable to create directory in up level directory.

Isn't there any information to be found in the apache's 'error_log' about this event?

Perhaps it is an 'open_basedir' issue, which can be set independently of safe_mode.

Kind regards,

Yes you are right! It the 'open_basedir' problem.

"Limit the files that can be opened by PHP to the specified directory-tree, including the file itself. This directive is NOT affected by whether Safe Mode is turned On or Off."

Plesk uses open_basedir param by default.
