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: “The .phtml files have a combination of HTML and PHP code and the .js files contain exclusively JavaScript code.”

A block of code is set as follows:

    public function getArrayCopy()

    {

        return get_object_vars($this);

    }

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 static function encrypt(String $text)

    {

        $text = strrev(hash('sha256', $text));

        return hash('md5', $text);

    }

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

Failed asserting response code "302", actual status code is "404"

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: “Save the file and click on the Update dependencies button.”
