Calling Functions Dynamically

Code:

<!--
   In PHP, you can call functions dynamically

   1.   Declare a function
   2.   Then declare a variable and assign the function name to the variable (as a string)
   3.   Then use the variable as a function
-->

<?php
  function addition ($a, $b){
      echo ($a + $b), "\n";
  }
  $result = "addition";
  $result (3,6);
?>
