Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "We can inherit other templates through the use of the extends() tag."

A block of code is set as follows:

public function aboutAction($name)
{
  $em = $this->container->get('doctrine')->getManager();
  $repo = $em->getRepository('ProjectBundle:Assignee');
  $photographer = $repo->findOneBy(array('name' =>$name));
  return $this->render('ProjectBundle:Default:about.html.twig',
                        array('Assignee' =>$Assignee));
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

public function aboutAction($name)
{
  $em = $this->container->get('doctrine')->getManager();
  $repo = $em->getRepository('ProjectBundle:Assignee');
 $photographer = $repo->findOneBy(array('name' =>$name));
  return $this->render('ProjectBundle:Default:about.html.twig',
                        array('Assignee' =>$Assignee));
}

Any command-line input or output is written as follows:

app/console doctrine:fixtures:load --append

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "in Symfonyprofiler page click on the Security button to see if the current user is authenticated".
