Discussion on: PHP crash course : Conditionals, Loops and Functions

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
