Meaning of cache:clear config:clear

cache:clear clears your application cache, no matter how it is configured (files, database etc.). It has nothing to do with configs.

config:clear deletes your cached config files. By default it's /bootstrap/cache/config.php. Laravel tries to read config from that file if it exists. Otherwise it reads your config from /config folder.

I didn't get it Can you give me some real world example so that I can try and understood it

I'm not sure what is it that you don't understand. I assume you are a Laravel beginner, so the best path for you is to just get through the docs.

You know what cache is, right.

If not you can Google that word read the definition then you will understand.

I know meaning of cache but i want to know practically in laravel. Can you give me some example

config:clear you haven't figured out that configuration is cached.

So what do you think config:clear does.

Okay you make a configuration change for example you now have a new password for your database

Now to ensure that you are using current configuration, okay do you see now.

Just curious, did you try:

php artisan help config:clear

which gives:

Description:

  config:clear
