why is this php code returning 2 even though its incremented?

Question

<?php
$a=2; $b=$a++;
echo $b;
?>

why does it return 2.. i'm confused..

Answer 1

That increment placement is postfix, you'll want to use prefix instead. Meaning, $b is assigned to value $a and then incremented after. Writing $b = ++$a will increment before assigning the value and you'll get the result you're looking for.

Answer 2
