Check if number is Odd or Even

Check if number is Odd or Even

Here we have a simple function that returns TRUE or FALSE when checking if an INT is odd or even.



<?php
/**
* number to check
*/$num = 3;
/**
*
* @Check if number is odd or even
*
* @var $num The number to check
*
* Return BOOL
*
*/function checkNum($num){
  return ($num%2) ? TRUE : FALSE;
}

if(checkNum($num) === TRUE){
  echo 'its odd';
}else{
  echo 'its even';
}  ?>
