If number divided by 2 and remainder is zero , that number is even number.
8 is divided by 2 and reminder is zero , this is even number
8/2 = 4
4/2 = 2
2/2 = 0 (remainder)

5 is odd number

5/2 = 2.5
2.5 /2 = 1.25 (remainder)

if remainder = 0 , that number is even number

In php % (Modulus result is Remainder of $a divided by $b ) operator used to find remainder value

if (($i % 2) == 0 ) {
  echo "$i is even";
} else {
  echo "$i is odd";
}

} else {
    echo "8 is even";
}
