$S_SESSION variable not staying set and failing 'isset' check

In my PHP file, I want to call a function to return a string variable. But I only want to call this function once, not when the page is re-loaded. So I'm using S_SESSION but checking if it is set is not working and is always calling my function.

Code snippet I'm using is below:

<?php
session_start();

include ("include/connection.php");
include ("include/functions.php");

function find_session_word() {
  //Open the file.
  $myfile = fopen("french.txt", "r") or die("Unable to open dictionary file.");

  $f_contents = file("french.txt");

  //Get a random line from the file.
  $line = $f_contents[array_rand($f_contents) ];

  fclose($myfile);

  return $line;
}

if (!isset($S_SESSION['session_word'])) {
  $S_SESSION['session_word'] = find_session_word();
}
?>

I would expect when I reload the page, the S_SESSION variable is set and the function is not called. But the function is called very time and I get a new word returned.

I have session_start() at the top of the file.

PHP sessions are stored in $_SESSION, not $S_SESSION [PHP manual].
