Answer 1

You need to execute following command:

.app/console doctrine:schema:create --dump-sql >schema.sql

And here's the answer how to run Command from Controller : How can I run symfony 2 run command from controller

Answer 2

Just to get you started, this should work in concept. I didn't get to run it, so I assume it might need a little tweaks from your side.

<?php
use Symfony\Component\Console\Input\ArrayInput;
use Symfony\Component\Console\Output\NullOutput;
use Doctrine\Bundle\DoctrineBundle\Command\Proxy\CreateSchemaDoctrineCommand;

// your controller

public function myAction()
{
    $command = new CreateSchemaDoctrineCommand();
    $command->setContainer($this->container);
    $input = new ArrayInput(array('--dump-sql' => true));
    $output = new NullOutput();
    $schema = $command->run($input, $output); //This is your schema

    // Write it to a file if you want
    file_put_contents('path/to/schema.sql', $schema);
}
