Pellentesque et sapien pulvinar consectetur. Nunc viverra elit ac laoreet suscipit. Sunt torquises imitari velox mirabilis medicinaes. Abnobas sunt hilotaes de placidus vita. Vae humani generis. Silva de secundus galatae demitto quadra. Potus sensim ad ferox abnoba. Curabitur aliquam euismod dolor non ornare. Era brevis ratione est. Ubi est audax amicitia.

This is a demo application built in the Symfony Framework to illustrate the recommended way of developing Symfony applications.

src/Controller/BlogController.php at line 272

/**
 * NOTE: when the controller argument is a Doctrine entity, Symfony makes an
 * automatic database query to fetch it based on the value of the route parameters.
 * The '{slug:post}' configuration tells Symfony to use the 'slug' route
 * parameter in the database query that fetches the entity of the $post argument.
 * This is mostly useful when the route has multiple parameters and the controller
 * also has multiple arguments.
 * See https://symfony.com/doc/current/doctrine.html#automatically-fetching-objects-entityvalueresolver.

    // Symfony's 'dump()' function is an improved version of PHP's 'var_dump()' but
    // it's not available in the 'prod' environment to prevent leaking sensitive information.
    // It can be used both in PHP files and Twig templates, but it requires to
    // have enabled the DebugBundle. Uncomment the following line to see it in action:

    // dump($post, $this->getUser(), new \DateTime());
    //
    // The result will be displayed either in the Symfony Profiler or in the stream output.
    // See https://symfony.com/doc/current/profiler.html

    // You can also leverage Symfony's 'dd()' function that dumps and
    // stops the execution
