# Bridge collectors DebugBar comes with some "bridge" collectors. This collectors provides a way to integrate other projects with the DebugBar. ## CacheCache http://maximebf.github.io/CacheCache/ Displays cache operations using `DebugBar\Bridge\CacheCacheCollector` $cache = new CacheCache\Cache(new CacheCache\Backends\Memory()); $debugbar->addCollector(new DebugBar\Bridge\CacheCacheCollector($cache)); CacheCache uses [Monolog](https://github.com/Seldaek/monolog) for logging, thus it is required to collect data. `CacheCacheCollector` subclasses `MonologCollector`, thus it can be [aggregated in the messages view](base-collectors.html#messages). ## Doctrine http://doctrine-project.org Displays sql queries into an SQL queries view using `DebugBar\Bridge\DoctrineCollector`. You will need to set a `Doctrine\DBAL\Logging\DebugStack` logger on your connection. $debugStack = new Doctrine\DBAL\Logging\DebugStack(); $entityManager->getConnection()->getConfiguration()->setSQLLogger($debugStack); $debugbar->addCollector(new DebugBar\Bridge\DoctrineCollector($debugStack)); `DoctrineCollector` also accepts an `Doctrine\ORM\EntityManager` as argument provided the `SQLLogger` is a ̀DebugStack`. ## Monolog https://github.com/Seldaek/monolog Integrates Monolog messages into a message view using `DebugBar\Bridge\MonologCollector`. $logger = new Monolog\Logger('mylogger'); $debugbar->addCollector(new DebugBar\Bridge\MonologCollector($logger)); Note that multiple logger can be collected: $debugbar['monolog']->addLogger($logger); `MonologCollector` can be [aggregated](base-collectors.html#messages) into the `MessagesCollector`. ## Propel http://propelorm.org/ Displays propel queries into an SQL queries view using `DebugBar\Bridge\PropelCollector`. You will need to activate Propel debug mode. // before Propel::init() $debugbar->addCollector(new DebugBar\Bridge\PropelCollector()); Propel::init('/path/to/config'); // after Propel::init() // not mandatory if you set config options by yourself DebugBar\Bridge\PropelCollector::enablePropelProfiling(); Queries can be collected on a single connection by providing the `PropelPDO` object to the `PropelCollector` as first argument. ## Slim http://slimframework.com Displays message from the Slim logger into a message view using `DebugBar\Bridge\SlimCollector`. $app = new Slim\Slim(); $debugbar->addCollector(new DebugBar\Bridge\SlimCollector($app)); ## Swift Mailer http://swiftmailer.org/ Display log messages and sent mail using `DebugBar\Bridge\SwiftMailer\SwiftLogCollector` and `DebugBar\Bridge\SwiftMailer\SwiftMailCollector`. $mailer = Swift_Mailer::newInstance(Swift_NullTransport::newInstance()); $debugbar['messages']->aggregate(new DebugBar\Bridge\SwiftMailer\SwiftLogCollector($mailer)); $debugbar->addCollector(new DebugBar\Bridge\SwiftMailer\SwiftMailCollector($mailer)); ## Twig http://twig.sensiolabs.org/ Collects info about rendered templates using `DebugBar\Bridge\Twig\TwigCollector`. You need to wrap your `Twig_Environment` object into a `DebugBar\Bridge\Twig\TraceableTwigEnvironment` object. $loader = new Twig_Loader_Filesystem('.'); $env = new DebugBar\Bridge\Twig\TraceableTwigEnvironment(new Twig_Environment($loader)); $debugbar->addCollector(new DebugBar\Bridge\Twig\TwigCollector($env)); You can provide a `DebugBar\DataCollector\TimeDataCollector` as the second argument of `TraceableTwigEnvironment` so render operation can be measured.
