PHP modulus in action

modulus.php

<?php
  // % is modulus; it takes $object, divides by 5 and looks at the remainder
  // It's a good way to find the nth item in an array for PHP
  $object = 20;
  
  // Case 1
  // in this case 20/5 = 4.0, making the remainder 0, satisfying the if case
  // result: $boo = true
  if ($object % 5 == 0) { 
    $boo = true;
  } else {
    $boo = false;
  }
  
  // Case 2
  // in this case 20/8 = 2.5, making the remainder 0 and not satisfying the if case  
  // result: $boo = false
  if($object % 8 == 0) {
    $boo = true;
  } else {
    $boo = false;
  }
