What is Laravel Tinker? how to use?

Introduction to Laravel Tinker

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

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

In addition, you can also use PsySH . Compared with the native php -a, PsySH has more advanced features and is more powerful.

Install globally through Composer:

composer g require psy/psysh:@stable

Then execute psysh on the command line to enter the interactive shell (you need to ensure that the bin of global Composer is directory in the system path), you can write various codes in PsySH, print statements, calculate expressions, write functions, etc.

Laravel Tinker is implemented based on PsySH. Through Tinker, we can realize various interactions with Laravel applications on the command line, including additions, deletions, modifications and queries of the database.

You can enter the interactive shell of Laravel Tinker through php artisan tinker on the command line.

View help documentation

In Laravel Tinker, the doc command can be used to view the help documentation for a certain function or method, for example, view the helper functionconfig( ) How to use:

doc config

show config

Run Artisan command

Runphp artisan tinker is equivalent to starting the Laravel application from the console, before running the interactive command , the tinker command will add some commands to the Shell, these commands are defined in the $commandWhitelist attribute of Laravel\Tinker\Console\TinkerCommand:

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

So, these commands can be run directly in the 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 this Records.

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');
