I had my exam today and I got a question on session and cookies. I watched this video in the morning. Because of your video I could answer that question. Thank you 🙏💕

A tip for writing the expiration-time is to, instead of writing it in seconds, write it in a more comprehendable manner: SYNTAX: time() + seconds * minutes * hours * days Example for a cookie that lasts a week (7 days): time() + 60 * 60 * 24 * 7

So should I use 86.400 or 86.400.000 for one day?

@nrnugteren 6 жыл бұрын

Good question +Vinicius Valente, was wondering the same. 24 hours * 60 minutes * 60 seconds is 86.400 seconds, but how does PHP interpret that number? EDIT (found the answer): Just found the answer on php.net/manual/en/function.setcookie.php "expire The time the cookie expires. This is a Unix timestamp so is in number of seconds since the epoch. In other words, you'll most likely set this with the time() function plus the number of seconds before you want it to expire." In other words: Daniel has set the value correctly in this tutorial, if he wants the cookie to be expired after 1 day.

@xiaoti8035 4 жыл бұрын

bullshit, 86400 seconds and 86400000 milliseconds would be 172,800 seconds. there are only 86400 seconds in a day OR 86400000 milliseconds. Please,man your in the coding world, syntax is important. JK

@atmian 10 ай бұрын

Good info. However, 1 day = 86400 seconds, not milliseconds as you said. So should seconds or milliseconds be used for cookie time? If milliseconds, you should enter 86400000 instead.

Great videos 👍 In this video you mentioned that usernames/passwords should be stored in sessions and that sessions end as soon as you close the browser. But When I go to a website that needs me to login, I can close the site and then go back and still be logged in. Does that mean that site is using cookies to store my username and password? Or is there something else they're using to remember my username and password?

Thank you Danial for such great series. Do we you what is the id of a user when we assign value for session ? If yes how do we know ?

@nrnugteren 6 жыл бұрын

If I had to guess (not there yet, but from my previous slight experiences with MySQL): The ID (for example '12') corresponds with an ID in a database, they you either create manually or that is being assigned automatically upon user creation. In that table you will have one row with ID's (i.e. 1 to 20) and the row next to it has the usernames corresponding to those ID's. Anyone feel free to correct me if I'm wrong, but I think that's how it will work when we arrive at the tutorial about databases and login systems.

Would there be a reason why a session may drop before a session destroy and don't close the browser? Im using PHP 5.5.4 on xamp package 1.8.3, and I cannot for the life of me work out why sessions could drop without either of the aforementioned events happening.

First of all, you have the best php tutorials on youtube! :D Secondly, I was wondering if it's possible to share a session between two or more users. Here is what I mean. Let's say we have a $_SESSION['room'] (which stores a multidimensional array) is it possible to share a reference to this session between two users? I tried something like generating a random name for the room and store it inside a variable called $room_id and than I started a session $_SESSION[$room_id] but of course it didn't work :). Thanks in advance!

Turns out you have to start a session on each new page that is executed and in the page where you are setting session variables BEFORE you set them (I think he shows this in the next video, but anyway..) -----index.php----- if (!isset($_SESSION)) { session_start(); } $_SESSION['name'] = 'Daniel; -----test.php----- if (!isset($_SESSION)) { session_start(); } echo $_SESSION['name'];

I don't get it.. Why should we make the time negative when deleting a cookie instead of just removing the line of code??

@Dani_Krossing 3 жыл бұрын

If you delete a line of code, it will get deleted for all the users using the site. And because PHP is a language used to make dynamic content on web sites, it defeats the purpose. 🙂 Look at it this way... If you have vending machine that people can get a variety of snacks from. Deleting the line of code would be the same as stopping the machine from being able to sell, let’s say chips, to ALL customers. Not just to some of the them. Instead we need the customers to be able to buy chips, but also cancel their purchase if needed. And that’s why we have statements in PHP to determine “if the customer wants chips” as well “if they want to cancel their order”.
