How to load and view Content with the eZ Platform PHP API

This is a code example from the eZ Publish / eZ Platform API Cookbook on how to search and find Content using the eZ Publish content API in Symfony Controllers or Commands:

/**
 * This command loads a Content using its numerical identifier, iterates over the Content's Fields, and shows the value
 * of each of them.

                $output->writeln( $valueHash );
            }
        }
        catch ( \eZ\Publish\API\Repository\Exceptions\NotFoundException $e )
        {
            $output->writeln( "<error>No content with id $contentId found</error>" );
        }
        catch ( \eZ\Publish\API\Repository\Exceptions\UnauthorizedException $e )
        {
            $output->writeln( "<error>Permission denied on content with id $contentId</error>" );
        }
    }
