Description:
------------
(PHP5.5.9) In creating a directory using "mkdir('./results/16/07/22/G2/4', 0777, true), all but the last (4) subdirectory is created. The function returns true, no exception is thrown. This happens when the PHP script containing the line is run on an Apache2.4/7 web server. When the same function is run in interactive PHP, it works fine. safe_mode is off in both php.ini files. I substituted the CreateDirPath() function for it, but I get the same behavior on the server and interactively.

Test script:
---------------
$test['path'] = './results/16/07/22/G2/4';
mkdir($test['path'], 0777, true);

  -- and --

function CreateDirPath($dirpath, $rwx = 0777)
{ $x = preg_replace('/\.\//', '', $dirpath);
  $dlst = explode('/', $x);
  $cwd = $xdir = getcwd();

  try
  { foreach ($dlst as $d)
    { $dt = trim($d);

      if ($dt)
      { $xdir = "$xdir/$dt";
        if (!is_dir($xdir))
        { if (!mkdir($dt, $rwx)) return false;
        }

        if (!chdir($xdir)) return false;
      }
    }

    return chdir($cwd);
  }
  catch(Exception $e) { return false; }
}


Expected result:
----------------
I expect all the directories to be created with a permission of 0777.
CreateDirPath() does this interactively, but behaves the same as mkdir() when run under Apache.
