Web shell allows to run yii console commands using a browser.

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist samdark/yii2-webshell "~1.0" 

or add

"samdark/yii2-webshell": "~1.0" 

to the require section of your composer.json file.

To use web shell, include it as a module in the application configuration like the following:

return [ 'modules' => [ 'webshell' => ['class' => 'samdark\webshell\Module'], ], ]

With the above configuration, you will be able to access web shell in your browser using the URL http://localhost/path/to/index.php?r=webshell
