Question

Doctrine can generate entities based on small data input, including relation information. However, i have failed to find any example or concise information on the topic. The official documentation only has a small paragraph, with a minor command line example, explaining absolutely nothing,

Can anyone refer to a book, article or even code sample of this?

First you need to bootstrap Doctrine and get an instance of EntityManager, then you once you have it, you can do the following:

    $cmf = new Doctrine\ORM\Tools\DisconnectedClassMetadataFactory();
    $cmf->setEntityManager($em); // $em is EntityManager instance
    $metadata = $cmf->getAllMetadata();
    $generator = new \Doctrine\ORM\Tools\EntityGenerator();
    $generator->setGenerateAnnotations(true);
    $generator->setGenerateStubMethods(true);
    $generator->setRegenerateEntityIfExists(true);
    $generator->setUpdateEntityIfExists(false);
    $generator->generate($metadata, '/path/to/entities');
