Check If All Digits of a Number Divide It in PHP

To check if all digits of a number divide it in PHP, the code is as follows −

Example

 Live Demo

<?php
function divisibility_check($my_val, $my_digit)
{
   return ($my_digit != 0 && $my_val % $my_digit == 0);
}
function divide_digits($n)
{
   $temp = $my_val;
   while ($temp > 0)
   {
      $my_digit = $my_val % 10;
      if (!(divisibility_check($my_val, $my_digit)))
         return false;
      $temp /= 10;
   }
   return true;
}
$val = 255;
if (divide_digits($val))
   echo "All the numbers can be divided";
else
   echo "All the numbers can't be divided";
?>

Output

All the numbers can be divided

A function named ‘divisibility_check’ is defined that checks to see if the number is not 0 and if the number completely divides every digit of the number, without leaving any value as a remainder. Another function named ‘divide_digits’ is defined that checks to see if every digit in the number divides the number completely. The number is defined, and the ‘divide_digits’ function is called by passing this number as the parameter. Relevant message is displayed on the console.
