access root folder

[smartic]

is code are ok or not [PHP]$_SERVER['DOCUMENT_ROOT'].'armese_data/call/call.php'[/PHP] to access the root folder for security from downloading the files by direct url.

if i not mistake, in Linux environment $_SERVER['DOCUMENT_ROOT'] will not append / at last character at default directory path.

what is the alternative for this code to access the root folder?

The root folder of what?

If you want to access the root directory of your Linux system, simply appending / to any path will jump to the root directory
For example: "/var/www/html"

If you want the web-root, meaning the top level directory accessible from your HTTP server, you could do:

$_SERVER['DOCUMENT_ROOT'] . "/path/to/file.ext"

my point is how can i access files by php outside the public_html folder like files i want only registerd users only to access it or files i use it for my connection with DB ?

PHP can access any file on the server's file-system, granted that it has the proper permission.
You can use absolute paths with most of PHP's file functions, such as include and readfile.

Like, say, if you had a DB connection script stored in "/var/www/include", you could simply do:
[code=php]
include("/var/www/include/dbConnect.php") ;
[/code]
If your web-root is located at "/var/www/html", and the current script is at the web-root, you could also use a relative path, like:
[code=php]
include("../include/dbConnect.php") ;
[/code]
On Windows, using a path like "C:\\SomeDir\my file.php" should also be perfectly valid.
