I have an spl_autoload function registered in my base controller and

$rootDirectory = new \Sabre_DAV_FS_Directory($rootDir);
// The server object is responsible for making sense out of the WebDAV

$server = new \Sabre_DAV_Server($rootDirectory);
However, SabreDAV it's self has a large amount of other PHP classes
which it calls which obviously aren't prefixed with '\'
Is there a way i can tell PHP any class name that get's instanciated
with 'Sabre_' should resolve to '\Sabre' ?
Many thanks

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
)

Richard.

[PHP] Namespaced code with SabreDAV

Many thanks Andrew If my memory serves regarding PHP's namespace, you could build something like this $file = APP_DIR.'\'.$class; if( file_exists( $file ) ) require_once $file; into your autoloader. You may have to adjust '/' to/from '\\' depending on your platform or you can use the constant DIRECTORY_SEPARATOR in the full path to the class. Then you don't need add \ before your class to instantiate. I don't know how the SabreDAV framework looks like but you may want to look at how Zend framework loads their class as to give you some idea what you may need to do in your autoload to circumvent SabreDAV being not 5.3 namespace declaration. You may also want to take a look at CodeIgniter's autoloading mechanism. Regards, Tommy

Here's another idea that you could do with the autoloader. The autoloader
is slightly modified from PureMVC's site to suit my needs. Using namespace
and everything that's PHP v5.3+, this is part of PureMVC framework that I've
ported over from the original Flash code a while back.
define( 'PMVC_BASE_DIR', str_replace( '\\', '/', __DIR__ ).'/' );
function __autoload( $class )
{
if( stristr( $class, '\\' ) )
{
$file = APP_DIR.str_replace( '\\', '/', $class ).EXT;
if( file_exists( $file ) ) require_once $file;
else throw new \Exception( 'Unable to find class '.$class.
' in the expected location '.$file );
} else
{
$_basePaths = array(
PMVC_BASE_DIR.'org/puremvc/php/patterns/facade/',
PMVC_BASE_DIR.'org/puremvc/php/interfaces/',
PMVC_BASE_DIR.'org/puremvc/php/core/',
PMVC_BASE_DIR.'org/puremvc/php/patterns/',
PMVC_BASE_DIR.'org/puremvc/php/patterns/command/',
PMVC_BASE_DIR.'org/puremvc/php/patterns/mediator/',
PMVC_BASE_DIR.'org/puremvc/php/patterns/observer/',
PMVC_BASE_DIR.'org/puremvc/php/patterns/proxy/' );
$classPaths = array_merge( explode( PATH_SEPARATOR,
get_include_path() ), $_basePaths );
foreach( $classPaths as $classPath )
{
$path = $classPath.$class.EXT;
if( file_exists( $path ) )
{
require_once $path;
return;
}
}
throw new \Exception( 'Unable to find class '.$class.' in '.
implode( PATH_SEPARATOR, $classPaths ) );
}
}
