There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “From the Symfony world, Laravel includes packages such as Symfony/routing to manage routing, and http-foundation and http-kernel to manage HTTP communication.”

A block of code is set as follows:

        "nyholm/psr7": "^1.5",
        "spiral/roadrunner": "v2.0"

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

command=/usr/bin/php -d variables_order=EGPCS /var/www/html/artisan octane:start --server=swoole --host=0.0.0.0 --port=80 --watch

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

npm install --save-dev chokidar

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Once everything is fine, you will see Table created! on your web page. This means that the rows were created in the right way.”
