Laravel - Artisan Console - Options

Options, like arguments, are another form of user input. Options are prefixed by two hyphens (--) when they are provided via the command line. There are two types of options: those that receive a value and those that don't. Options that don't receive a value serve as a boolean "switch". Let's take a look at an example of this type of option:

     * The name and signature of the console command.
     * @var string
    protected $signature = 'mail:send {user} { --queue}';

In this example, the --queue switch may be specified when calling the Artisan command. If the --queue switch is passed, the value of the option will be true. Otherwise, the value will be false:

    php artisan mail:send 1 --queue
