I already knew that, I've learned the hard way... after 4hrs of debuggin 😅

Nice! + Also you can create your own config file too instead of putting them in config.php if you have a lot of custom configuration fields.

Your tips helped me out when I was starting out with laravel development. Especially those old articles you have on your website. I've been recommending your channel ever since.

On every deployment, i run the command:
php artisan optimize:clear
Which clears:
Cached config
Cached views
Cached routes
...
or run the command:
php artisan optimize
which clears all the cached config, views...
And create a new cache for all.

Thank you for everything! The channel's amazing!

Thank you, Povilas. I've always know it was best practice to use config and only ever use the env() function from within your configuration files, but I never bothered to question why that was and see demonstrations of issues it can lead to. One thing your video has taught me is that I should start using config cache on my applications and will be doing so in the near future.

A classic case of premature optimization. I wish the Laravel team made the config cache optional, instead of loading it by default.

Aaaahh .. now I know why everytime I use artisan config:cache I hit the wall 😂 Thank for the tip! 👍

[GamePlayByFaks]

env, tends to be empty due to cache and cause hell of fun :)) (if recall correctly this issue appeared in laravel 7 or 8, since in core were changed introduced)

[Stoney_Eagle]

I used to use env until laravel started to cache by default and it broke everything 😂😂

[resin]

Awesome. I see people do this constantly. I will link to this video instead of the docs from now on 👍

[padvk]

Why doesn't the env function load the cached value when used in a controller? Is that purposeful design?

[MaxRomagnoli]

You convinced me to use config instead of env out of laziness

[resin]

Can I recommend renaming the video to "Why you should not use env() outside of Laravel config files?". The same problem is present in all files except config files :)

[enmaboya]

thanks!

what about the unit / feature tests?
do we use only config() there, too ?

[jfordgaming]

yeah I've experience with this implementation before must be in config.

[bernardocampos]

How much faster goes the app after running config:cache?🤔

[llBestBoyll]

short trick and super informative
thx ❤️🔥

[tetleyk]

So, here's a question. Just how much of a performance boost is gained when caching the values compared to using the env() function? I've seen this claim many times but not a single instance (yet) of someone testing it.

I'm an engineer, I need proof. You (and others) say it's faster? Prove it!

Yes, I know I can do that myself but if you or someone on Youtube carries out the test, then it will be available for all to see.

This is helpful, i will give it a try and see where it's getting stored and the time difference between cached vs non-cached config for our one of the full-blown project
