I’m a noob programmer so I apologies in advance for any obvious mistakes. I’ve spent the past week creating a product database kinda thing. I’ve got too the point where I can add products using a form, view all products added etc. I’ve being using sessions which are created via the form input data. I’m struggling to include get a delete product page working, I’ve tried using unset to clear the variable but can’t get it too work.
ADD Product page which sets the session variable:
$_SESSION['Products'][] = $_POST; //is how i set the session on the add products page. unset $_SESSION['Products'][]; //is how i have tried to clear the session although it does not work.
Any point in the right direction will be appreciated!

Answer
You can unset session variable using:
session_unset
– Frees all session variables (It is equal to using:$_SESSION = array();
for older deprecated code)unset($_SESSION['Products']);
– Unset only Products index in session variable. (Remember: You have to use like a function, not as you used)session_destroy
— Destroys all data registered to a session
To know the difference between using session_unset
and session_destroy
, read this SO answer. That helps.
