The use of Laravel Tinker

Introduction to Laravel Tinker

In native PHP, you can use interactive Shell with the php-a command:

# php-aphp > $msg = "Hello world!"; php > print $msg;Hello Worldwide php > $num = array_sum ([1,2,3]); php > print $num;6

In addition, you can use PsySH, which has more advanced features and more power than the native php-a _ Psysh.

Global installation via Composer:

Composer g require psy/psysh:@stable

Then execute psysh on the command line to enter the interactive Shell (make sure that the bin directory of the global Composer is in the system path), where you can write all kinds of code, print statements, evaluate expressions, write functions, and so on.

Laravel Tinker is based on PsySH. Through Tinker, we can interact with Laravel applications on the command line, including database additions, deletions, modifications and queries.

You can enter Laravel Tinker's interactive Shell through php artisan tinker on the command line.

View help documentation

In Laravel Tinker, the doc command can be used to view help documentation for a function or method, for example, to see how the helper function config () is used:

Doc configshow config runs the Artisan command

Running php artisan tinker is equivalent to launching the Laravel application from the console. Before running interactive commands, the tinker command adds commands to Shell, which are defined in the $commandWhitelist attribute of Laravel\ Tinker\ Console\ TinkerCommand:

Protected $commandWhitelist = ['clear-compiled',' down', 'env',' inspire', 'migrate',' optimize', 'up',]

Therefore, you can run these commands directly in Tinker Shell:

> inspire > env testing Laravel code

You can use the console to create a new model, save it to the database, and then query the record.

Php artisan tinker > > migrate > use App\ User; > > $user = new User (); > > $user- > name = "test"; > $user- > email = "test@163.com"; > > $user- > password = bcrypt ('123456'); > > $user- > save (); > > $user = User::where (' email', 'test@163.com')-> first (); > > factory (User::class, 3)-> create (); > $user = App\ User::find (1); > $user- > delete (); > $log = app (log') > $log- > info ('test'); at this point, the study on "how to use Tinker in Laravel" is over.
