// define $total variable.
@php $total = 0 @endphp
@php
$total += $details['price'] * $details['quantity']
@endphp
$total += 10;
is equivalent to
$total = $total + 10; // but $total is undefined

@LoverToHelp it this just an IDE "error"?
You could compute the total outside the loop:
{{ array_reduce(session('cart'), fn ($total, $item) => $total += $item['price'] * $item['quantity'], 0) }}
Although, I'd suggest calculating this value in the Controller rather that in the Blade template

You have not initialized $total
@php($total = 0)
@foreach (session('cart') as $id => $details)
@php $total += $details['price'] * $details['quantity'] @endphp

Level 104
@LoverToHelp remember, no ¯\_(ツ)_/¯
Anyway, is this just an IDE error, or is it not working in the Browser?

@tykus Before, by reducing the amount of input, the total amount also changes, now I find something else. Oh, the input is not in English. Maybe that is the reason/ see you next problem ;)
