These code snippets are not correct:

x$ = 10;

$sum = function ($a, $b) use $x (
    return $x + $a + $b;
);

echo $sum(10, 15);
// 35

It should change into:

$x = 10;

$sum = function ($a, $b) use $x (
    return $x + $a + $b;
);

echo $sum(10, 15);
// 35

a mix php with html is not a good way to show a modern php :) but I left heart for making php more popular these times :)

Php started as templating language so totally ok.

yep, that was, but it's not an example of modern PHP nowadays, that was what I meant

You don't work with frameworks like Magento 2, I assume? Using PHP as templating language is quite common and not in any way not modern.

I agree templating is can be part in any language especially in PHP

when u say modern php what do u mean , native php or frameWorks ?

REST API, no matter which framework

the if statement, checking if a string is valid, should always be === since its always same type

Good point I made the change. Thanks for your comment.

The $ position I think it's not correct: Shipping 9.95$.

I think it should be Shipping $9.95.
