+Some Insights support automatic fixing. 
+To fix your code automatically, two way are possibles: 
+

+```bash
+# Classical command with --fix option
+vendor/bin/phpinsights analyse path/to/analyse --fix

+# In laravel
+php artisan insights path/to/analyse --fix
+
+# Just fix
+vendor/bin/phpinsights fix path/to/analyse
+```
