如何在index.php文件中使用config（）函数？

Question

I use Laravel framework. I need to use config() function in the index.php file (which exists in the public folder). But when I call it, it throws this error:

Fatal error: Call to undefined function config() in C:\\xampp\\htdocs\\myproject\\public\\index.php on line 2

How can I fix it?

Answer 1

I'll not be able to use config() in index.php if no functionality were loaded at this point.

What you can do is to create simple functionality which will load data you need from config file. Or you can just hardcode value in index.php . But I'd recommend you to find another way to achieve your goal and not touch index.php at all.

Update Laravel has already have maintenance mode functionality.

Answer 2

This is because Config facades may not introduce for this index.php. You add use Illuminate\\Support\\Facades\\Config; to use Config method.

UPDATE
Instead of Config Try var_dump(getenv('APP_ENV')); , will help to use environment variable.
