How to set the correct quantity invoice?

Question

PHP

I set the number 4 but counts up to 5. How can I make the count stop at a given number? Thanks in advance !

$row = mysqli_fetch_array($data);
$new_count = $row["cart_count"];
$new_count++;
if ($new_count >= 1 & $new_count <= 4 ){ . . .

Answer 1

$new_count <= 4 Remove the equals
sign.

Answer 2

nothing is clear from the code, but apparently you first increase, and therefore you check.
And you need $new_count++; put inside conditions.
Plus logical AND is two amersands, &&, not one
