Jackalope is a powerful implementation of the PHP Content Repository API (PHPCR).
Jackalope-Jackrabbit is using the jackrabbit JCR server as storage engine.

The recommended way to install jackalope is through composer.
$ mkdir my-project $ cd my-project $ composer init $ composer require jackalope/jackalope-jackrabbit
Jackrabbit storage server
Besides the Jackalope repository, you need the Jackrabbit server component. For instructions, see Jackalope Wiki Make sure you have at least the version specified in the VERSION constant of the protocol implementation
If you want to run the tests, please see the README file in the tests folder and check if you told composer to install the suggested dependencies (see Installation)
Enable the commands
There are a couple of useful commands to interact with the repository.
To use the console, copy cli-config.php.dist to cli-config.php and configure
the connection parameters.
Then you can run the commands from the jackalope directory with
NOTE: If you are using PHPCR inside of Symfony, the DoctrinePHPCRBundle provides the commands inside the normal Symfony console and you don't need to prepare anything special.
There is the Jackalope specific command
jackalope:run:jackrabbit which you
can use to start and stop a jackrabbit standalone server.
You have many useful commands available from the phpcr-utils. To get a list of all commands, type:
To get more information on a specific command, use the
help command. To learn
more about the
phpcr:workspace:export command for example, you would type:
./bin/jackalope help phpcr:workspace:export
Jackalope relies on autoloading. Namespaces and folders are compliant with
PSR-0. You should use the autoload file generated by composer:
If you want to integrate jackalope into other PSR-0 compliant code and use your
own classloader, find the mapping in
Once you have autoloading, you need to bootstrap the library. A minimalist sample code to get a PHPCR session with the jackrabbit backend:
$jackrabbit_url = 'http://127.0.0.1:8080/server/'; $user = 'admin'; $pass = 'admin'; $workspace = 'default'; $factory = new \Jackalope\RepositoryFactoryJackrabbit(); $repository = $factory->getRepository( array("jackalope.jackrabbit_uri" => $jackrabbit_url) ); $credentials = new \PHPCR\SimpleCredentials($user, $pass); $session = $repository->login($credentials, $workspace);
To use a workspace different than
default you need to create it first. The
easiest is to run the command
bin/jackalope phpcr:workspace:create <myworkspace>
but you can of course also use the PHPCR API to create workspaces from your code.
The entry point is to create the repository factory. The factory specifies the storage backend as well. From this point on, there are no differences in the usage (except for supported features, that is).
// see Bootstrapping for how to get the session. $rootNode = $session->getNode("/"); $whitewashing = $rootNode->addNode("www-whitewashing-de"); $session->save(); $posts = $whitewashing->addNode("posts"); $session->save(); $post = $posts->addNode("welcome-to-blog"); $post->addMixin("mix:title"); $post->setProperty("jcr:title", "Welcome to my Blog!"); $post->setProperty("jcr:description", "This is the first post on my blog! Do you like it?"); $session->save();
See PHPCR Tutorial for a more detailed tutorial on how to use the PHPCR API.
Jackalope supports the PHPCR standard query language SQL2 as well as the Query Object Model (QOM) to build queries programmatically. We recommend using the QOM or the QueryBuilder mentioned in the PHPCR Tutorial. They are built to use the best possible query language depending on the capabilities of the backend. A later switching to another PHPCR implementation shouldn't cause any issues then.
Jackalope-Jackrabbit also supports the deprecated SQL and XPath query languages from JCR 1.0. Those languages will be supported by Jackrabbit for the foreseeable future, but almost certainly won't be supported by other PHPCR implementations. So use them with care and only if you know what you are doing.
One reason for using SQL or XPath is that the newer and more capable SQL2 is not as optimized as the older languages on the Jackrabbit side. Queries with large result sets are much slower with SQL2 than with XPath or SQL.
However, the best is to use the QueryBuilder mentioned above to let the implementation chose the most efficient query language for your implementation.
If you know that you will need many child nodes of a node you are about to request, use the depth hint on Session::getNode. This will prefetch the children to reduce the round trips to the database. It is part of the PHPCR standard. You can also globally set a fetch depth, but that is Jackalope specific: Call Session::setSessionOption with Session::OPTION_FETCH_DEPTH to something bigger than 1.
Use Node::getNodeNames if you only need to know the names of child nodes, but don't need the actual nodes. Note that you should not use the typeFilter on getNodeNames with jackalope. Using the typeFilter with getNodes to only fetch the nodes of types that interest you can make a lot of sense however.
Jackalope supports logging, for example to investigate the number and type of queries used. To enable logging, provide a logger instance to the repository factory:
$factory = new \Jackalope\RepositoryFactoryJackrabbit(); $logger = new Jackalope\Transport\Logging\DebugStack(); $options = array( 'jackalope.jackrabbit_uri' => $jackrabbit_url, 'jackalope.logger' => $logger, ); $repository = $factory->getRepository($options); ... // at the end, output debug information var_dump($logger->calls);
You can also wrap a PSR-3 compatible logger like monolog with the Psr3Logger class.
Note that when using jackalope in Symfony2, the logger is integrated in the debug toolbar.
See doc/architecture.md for an introduction how Jackalope is built. Have a look at the source files and generate the phpdoc.
Not implemented features
The best overview of what needs to be done are the skipped API tests. Have a look at ImplementationLoader to see what is currently not working and start hacking :-)
