Artisan command for clearing all session data in Laravel

问题

What is the artisan command for clearing all session data in Laravel, I'm looking for something like:

$ php artisan session:clear

But apparently it does not exist. How would I clear it from command line?

I tried using

$ php artisan tinker  
...
\Session::flush();

But it flushes session of only one user, I want to flush all sessions for all users. How can I do it?

I tried this:

artisan cache:clear

But it does not clear session, again.

回答1:

UPDATE: This question seems to be asked quite often and many people are still actively commenting on it.

In practice, it is a horrible idea to flush sessions using the

php artisan key:generate

It may wreak all kinds of havoc. The best way to do it is to clear whichever system you are using.

The Lazy Programmers guide to flushing all sessions:

php artisan key:generate

Will make all sessions invalid because a new application key is specified

The not so Lazy approach

php artisan make:command FlushSessions

and then insert

<?php

namespace App\Console\Commands;

use Illuminate\Console\Command;
use DB;

class flushSessions extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'session:flush';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Flush all user sessions';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        DB::table('sessions')->truncate();
    }
}

and then

php artisan session:flush

If you are using file based sessions, you can use the following linux command to clean the sessions folder out:

rm -f storage/framework/sessions/*

回答3:

An easy way to get rid of all sessions is to change the name of the session cookie. This can be easily done by changing the 'cookie' => '...' line in config/session.php file.

This works independently of the session storage you use and also won't touch any other data except the session data (and thus seems preferable over the renewing the app key solution to me, where you would loose any encrypted data stored in the app).

回答4:

This thread is quite much old. But I would like to share my implementation of removing all sesssions for file based driver.

        $directory = 'storage/framework/sessions';
        $ignoreFiles = ['.gitignore', '.', '..'];
        $files = scandir($directory);

        foreach ($files as $file) {
            if(!in_array($file,$ignoreFiles)) unlink($directory . '/' . $file);
        }

Why I have not used linux command 'rm'?

Because PHP is one of the prerequisites for Laravel and Linux is not. Using this Linux command will make our project implementable on Linux environment only. That's why it is good to use PHP in Laravel.

回答5:

The problem is that Laravel's SessionHandlerInterface does not force session drivers to provide any kind of destroyAll() method. Thus, it has to be implemented manually for each driver.

Taking ideas from different answers, I came up with this solution:

Create command

php artisan make:command FlushSessions

Create class in app/Console/Commands/FlushSessions.php

<?php

namespace App\Console\Commands;

use Illuminate\Console\Command;

class FlushSessions extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'session:flush';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Flush all user sessions';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        $driver = config('session.driver');
        $method_name = 'clean' . ucfirst($driver);
        if ( method_exists($this, $method_name) ) {
            try {
                $this->$method_name();
                $this->info('Session data cleaned.');
            } catch (\Exception $e) {
                $this->error($e->getMessage());
            }
        } else {
            $this->error("Sorry, I don't know how to clean the sessions of the driver '{$driver}'.");
        }
    }

    protected function cleanFile () {
        $directory = config('session.files');
        $ignoreFiles = ['.gitignore', '.', '..'];

        $files = scandir($directory);

        foreach ( $files as $file ) {
            if( !in_array($file,$ignoreFiles) ) {
                unlink($directory . '/' . $file);
            }
        }
    }

    protected function cleanDatabase () {
        $table = config('session.table');
        DB::table($table)->truncate();
    }
}

Run command

php artisan session:flush

Implementations for other drivers are welcome!
