I have PHP namespaced file

$cls = new foo();

Where is the foo class stored?

OR if exist __autoload() how to control directory mapping to namespace?

There is not direct relation between directories and namespaces, except if you use an autoloader.

If you want this code to works :

namespace A\B\C;
$cls = new foo();

You must do this : 

namespace A\B\C;
class foo {}
$cls = new foo();

Or do this :

foo.php

namespace \A\B\C;

class foo {}

index.php

require 'foo.php';

$cls = new \A\B\C\foo();
// or
namespace A\B\C;
$cls = new foo();

Now if you want to use autoloader, you can use something like this : 

function autoload($class)
{
    $class = str_replace('\\', '/', $class);

    require_once __DIR__ . '/' . $class . '.php';
}
spl_autoload_register('autoload');

Put this kind of code in top of your index.php and the get a dir arch like this : 

A
+ B
| + C
| | + foo.php

Then you just have to do : 

$cls = new \A\B\C\foo();

or even : 

use \A\B\C\foo;
$cls = new foo();

But anyway, YOU MUST READ MANUAL : Link here
