Just create a new artisan command with php artisan make:command LangFilesToJson and replace the content of the new empty class generated at app/Console/Commands with this one. Then you can use it by simply running at your terminal php artisan lang:json

I have also written a command so that I can run the PHP files recursively and the old synthax remains in the json file.
