I've just downloaded SabreDav 1.5.3

Put Sabre directory in my include path.

And using the following code, ...

<?php
namespace GoingToBeUsingSabre;

require_once 'Sabre/autoload.php';

var_dump(new \Sabre_DAV_FS_Directory('D:/'));
print_r(array_filter(get_declared_classes(), function($class){ return
'Sabre_' === substr($class, 0, 6);}));
print_r(get_included_files());
?>

outputs ...

object(Sabre_DAV_FS_Directory)#1 (1) {
  ["path":protected]=>
  string(3) "D:/"
}
Array
(
    [166] => Sabre_DAV_FS_Node
    [167] => Sabre_DAV_FS_Directory
)
Array
(
    [0] => Z:\UsingSabre.php
    [1] => D:\PHP\Includes\Sabre\autoload.php
    [2] => D:\PHP\Includes\Sabre\DAV\FS\Directory.php
    [3] => D:\PHP\Includes\Sabre\DAV\FS\Node.php
    [4] => D:\PHP\Includes\Sabre\DAV\INode.php
    [5] => D:\PHP\Includes\Sabre\DAV\ICollection.php
    [6] => D:\PHP\Includes\Sabre\DAV\IQuota.php
)

They provide their own autoloader. As you can see, I've included their
autoloader and made 1 call to a root namespaced class. The registered
autoloader took care of the rest and loaded the additional classes as
needed.

Take a look at the Zend Framework's autoloader
(http://framework.zend.com/manual/en/zend.loader.autoloader.html)

Here is the same working example, but using ZF's autoloader ...

<?php
namespace GoingToBeUsingSabre;

require_once 'Zend/Loader/Autoloader.php';
$o_ZendLoaderAutoLoader = \Zend_Loader_Autoloader::getInstance();
$o_ZendLoaderAutoLoader->registerNamespace('Sabre_');

var_dump(new \Sabre_DAV_FS_Directory('D:/'));
print_r(array_filter(get_declared_classes(), function($class){ return
'Sabre_' === substr($class, 0, 6);}));
print_r(get_included_files());
?>

output now is ...

object(Sabre_DAV_FS_Directory)#2 (1) {
  ["path":protected]=>
  string(3) "D:/"
}
Array
(
    [168] => Sabre_DAV_FS_Node
    [169] => Sabre_DAV_FS_Directory
)
Array
(
    [0] => Z:\UsingSabre.php
    [1] => D:\PHP\Includes\Zend\Loader\Autoloader.php
    [2] => D:\PHP\Includes\Zend\Loader.php
    [3] => D:\PHP\Includes\Sabre\DAV\FS\Directory.php
    [4] => D:\PHP\Includes\Sabre\DAV\FS\Node.php
    [5] => D:\PHP\Includes\Sabre\DAV\INode.php
    [6] => D:\PHP\Includes\Sabre\DAV\ICollection.php
    [7] => D:\PHP\Includes\Sabre\DAV\IQuota.php
)

Regards,

Richard.
