the define function with namespace

[ZER09]

I have a simple php library that i am using, now i wnat to upgrade it. I want to create namespace on it so my class will be inside on the namespaces bu t i got an error when i i tried to use namespace.

here a sample

<?php
    defined('protect')||(header("HTTP/1.0 404 Not Found"));

    require_once 'conf/configuration.php';
    class string{
        function __construct(){
            //some code;
        }

        //some function;
    }
    ?>

I used the defined function to protect the php file for direct accesss.
Now when i used namespace the code look like this.

<?php
    defined('protect')||(header("HTTP/1.0 404 Not Found"));
    namespace teststring;
    {
    require_once 'conf/configuration.php';
    class string{
        function __construct(){
            //some code;
        }

        //some function;
    }
    }
    ?>

now it will get an error surely because the namespace should be on the very first line. but when i put the defined function inside the namespace i think it cant protect the file from direct access, i already googled this but so far i got no good results.

i am asking how to protect my php files from direct access when i am using namespace?

I will appreciate for any help will come. thanks

btw sorry for my bad english

You can access globals with the backslash inside namespaces:

echo \protect;
