Why is this code giving 6 as the answer and not 5?

Question

<?php
$x = 2;
$y = ++$x;
echo $x + $y;
?> //result 6

Answer 1

Allan Khasenye
$X = 2 //initially
$y = ++x //due to pre increment first value increment then store so x become 3 and store in y by which y become 3 too
echo $x +$y // 3 + 3 =6
So output is 6

Answer 2

Because ++$x; is preincrement so the value of $x = 3, and that value is save to $y
Now $x and $y both has value 3
So 3+3 yields 6.

Answer 3
