Conventions used

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: “So, we will naturally create a service like UserRemover, which will perform these two tasks in a row.”

A block of code is set as follows:

class Example 
    public function doSomething() bool
        return true;

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

  "scripts": {
      "analyse": [
          "tools/vendor/bin/php-cs-fixer fix src",
          "tools/vendor/bin/phpstan analyse --level 1 src"
        "post-update-cmd": "composer update -d tools",
        "post-install-cmd": "composer update -d tools"

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

$ php phploc src

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: “Hovering the mouse pointer over TestClass will show a popup window with an explanation saying Undefined type TestClass.”
