First Reverse in php

gistfile1.txt

<?php 

function FirstReverse($str) {  

  // code goes here
  /*Here the built in function strrev() takes the value of $str
  as an argument and returns a reversed string */
  return strrev($str); 
}
   
// keep this function call here  
echo FirstReverse(fgets(fopen('php://stdin', 'r')));  

?>

Looks good. It’s nice to be able to solve a problem with a built-in like strrev, but also good to think about how to solve the problem without it.
