It provides a number of helpful commands that can assist you while you build your application.To view a list of all available Artisan commands, you may use the list command:.

Every command also includes a “help” screen which displays and describes the command’s available arguments and options.To view a help screen, simply precede the name of the command with help :.In addition to the commands provided with Artisan, you may also build your own custom commands.

To create a new command, use the make:command Artisan command.Don’t worry if this directory does not exist in your application, since it will be created the first time you run the make:command Artisan command.

The generated command will include the default set of properties and methods that are present on all commands:.Next, you will need to register the command before it can be executed via the Artisan CLI.After generating your command, you should fill in the signature and description properties of the class, which will be used when displaying your command on the list screen.

The handle method will be called when your command is executed.You may place your command logic in this method.In the example below, note that we inject a service class to do the “heavy lifting” of sending the e-mails.Let’s take a look at an example command.

Note that we are able to inject any dependencies we need into the command’s constructor.The Laravel service container will automatically inject all dependencies type-hinted in the constructor:.

Closure based commands provide an alternative to defining console commands as classes.In the same way that route Closures are an alternative to controllers, think of command Closures as an alternative to command classes.

Even though this file does not define HTTP routes, it defines console based entry points routes into your application.Within this file, you may define all of your Closure based routes using the Artisan::command method.The command method accepts two arguments: the command signature and a Closure which receives the commands arguments and options:.The Closure is bound to the underlying command instance, so you have full access to all of the helper methods you would typically be able to access on a full command class.

In addition to receiving your command’s arguments and options, command Closures may also type-hint additional dependencies that you would like resolved out of the service container :.When defining a Closure based command, you may use the describe method to add a description to the command.

This description will be displayed when you run the php artisan list or php artisan help commands:.When writing console commands, it is common to gather input from the user through arguments or options.Laravel makes it very convenient to define the input you expect from the user using the signature property on your commands.

The signature property allows you to define the name, arguments, and options for the command in a single, expressive, route-like syntax.All user supplied arguments and options are wrapped in curly braces.In the following example, the command defines one required argument: user :.

Options, like arguments, are another form of user input.Options are prefixed by two hyphens — when they are specified on 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:.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 :.Next, let’s take a look at an option that expects a value.

You may assign default values to options by specifying the default value after the option name.If no option value is passed by the user, the default value will be used:.To assign a shortcut when defining an option, you may specify it before the option name and use a delimiter to separate the shortcut from the full option name:.

First, let’s take a look at an example that specifies an array argument:.When calling this method, the user arguments may be passed in order to the command line.For example, the following command will set the value of user to [‘foo’, ‘bar’] :.When defining an option that expects an array input, each option value passed to the command should be prefixed with the option name:.

You may assign descriptions to input arguments and options by separating the parameter from the description using a colon.If you need a little extra room to define your command, feel free to spread the definition across multiple lines:.While your command is executing, you will obviously need to access the values for the arguments and options accepted by your command.

To do so, you may use the argument and option methods:.If you need to retrieve all of the arguments as an array , call the arguments method:.Options may be retrieved just as easily as arguments using the option method.To retrieve all of the options as an array, call the options method:.Sometimes you may wish to execute an Artisan command outside of the CLI.
