Installation and Configuration

Doctrine can be installed with Composer.

Define the following requirement in your composer.json file:

{
    "require": {
        "doctrine/orm": "*"
    }
}

Then call composer install from your command line. If you don't know how Composer works, check out their Getting Started to set up.

Class loading

Autoloading is taken care of by Composer. You just have to include the composer autoload file in your project:

<?php// bootstrap.php// Include Composer Autoload (relative to project root).require_once "vendor/autoload.php";

Obtaining an EntityManager

Once you have prepared the class loading, you acquire an EntityManager instance. The EntityManager class is the primary access point to ORM functionality provided by Doctrine.

<?php// bootstrap.phprequire_once "vendor/autoload.php";use Doctrine\ORM\Tools\Setup;use Doctrine\ORM\EntityManager;$paths = array("/path/to/entity-files");$isDevMode = false;// the connection configuration$dbParams = array(    'driver'   => 'pdo_mysql',    'user'     => 'root',    'password' => '',    'dbname'   => 'foo',);$config = Setup::createAnnotationMetadataConfiguration($paths, $isDevMode);$entityManager = EntityManager::create($dbParams, $config);

Or if you prefer XML:

<?php$paths = array("/path/to/xml-mappings");$config = Setup::createXMLMetadataConfiguration($paths, $isDevMode);$entityManager = EntityManager::create($dbParams, $config);

Or if you prefer YAML:

<?php$paths = array("/path/to/yml-mappings");$config = Setup::createYAMLMetadataConfiguration($paths, $isDevMode);$entityManager = EntityManager::create($dbParams, $config);

If you want to use yml mapping you should add yaml dependency to your composer.json:

"symfony/yaml": "*"

Inside the Setup methods several assumptions are made:

  • If $isDevMode is true caching is done in memory with the ArrayCache. Proxy objects are recreated on every request.
  • If $isDevMode is false, check for Caches in the order APC, Xcache, Memcache (127.0.0.1:11211), Redis (127.0.0.1:6379) unless $cache is passed as fourth argument.
  • If $isDevMode is false, set then proxy classes have to be explicitly created through the command line.
  • If third argument $proxyDir is not set, use the systems temporary directory.

If you want to configure Doctrine in more detail, take a look at the Advanced Configuration section.

You can learn more about the database connection configuration in the Doctrine DBAL connection configuration reference.

Setting up the Commandline Tool

Doctrine ships with a number of command line tools that are very helpful during development. You can call this command from the Composer binary directory:

$ php vendor/bin/doctrine

You need to register your applications EntityManager to the console tool to make use of the tasks by creating a cli-config.php file with the following content:

<?phpuse Doctrine\ORM\Tools\Console\ConsoleRunner;// replace with file to your own project bootstraprequire_once 'bootstrap.php';// replace with mechanism to retrieve EntityManager in your app$entityManager = GetEntityManager();return ConsoleRunner::createHelperSet($entityManager);
