Ok so, I've used session start before. It was more like I copied it. It wasn't explained in the video I watched. I just knew the guy wrote it at the top of the script. No understanding at all. So I'm very grateful for this video and also grateful to know that you talk about it more in the 3rd section. Thanks Gio.

Excellent work Sir... you pointed out each n every small small things, that no one talk about it...

Hi Gio - Love your course, I'm following every lesson. Thank you.
My question:
How would you manage that users session would stay active the whole day? Currently, the browser ends session after about 30 minutes or so of inactivity. My users log in and once logged in they refer to the app in different ways, but they don't sit there and look at the app, they multi-task and sometimes they are on a phone call - whatever it is, I must prevent the session from ending after non-activity - I only want the session to end at the end of the day.

Excellent as usual, just want to know how to copy the php.ini from wherever its source to the docker folder so I can edit things easily.. Google failed me on that so far Thanks again.

Awesome video !! ..
but I have a question, I set the PHP session cookie to httponly (in server settings) and indeed the httponly mark showed up..
but why when I type document.cookie in the console I can still see the cookie value ?

Thanks

Hi Gio, Some how, am not getting the increatment from $_Session['count']. Here are the codes:
Home Class inside the index(), i added $_SESSION['count'] = ($_SERVER['count'] ?? 0 )+ 1 ; and on the index page var_dump($_SESSION); I am getting only one on the browser, Using Nginx with PHP 8.1.9. Thanks for your anticipated response. Also, the buffering has been set to 0 from my php.ini file.

Hi Sir How are you, I need some help.I make a copy of the container php.ini on my host computer. If I change something in my host php.ini it doesn't change in container php.ini, how can I do that?

[mimlog]

Thanks for everything you do Gio, but please I would like to know how you are able to edit your php.ini file

[Kicaj]

Hi Gio, i dont get the fact we can't see the warning which is caused by having output_buffering > 0, start_session triggers E_WARNING, but if we do something like it also trigger E_WARNING but this time we will see in a browser Warning: So what's the difference between E_WARNING caused by start_session and include ?

[comounburro]

When is the third sections going to be released?

[momahdy]

Please tell me how does your app auto reflects code changes without the need to do a docker build

[AlexFloppy]

Do we have these code shared some where on github?

[bakosyy]

Hello Gio. Is it ok to also say that "Once RESPONSE is sent to a page, you can no longer send any further headers" instead of "Once HEADERS are sent to a page, you can no longer send any further headers"?
