PHP Returning Values help.

Although this particular PHP class doesn't present a code challenge, I do want to get this right. On the Returning Values code that Mr. Paulk has up, I swear, I have the same code. But he get's a value back and all I get is a blank screen. What am I doing wrong?

<?php

function add_up($a, $b){
 $arr = array{
   $a,
   $b,
   $a + $b
  };
  return $arr;
}

$value = add_up(2, 4);

print_r($value[2]);

?>

Forget it, found out the problem.

It should be this:

<?php

function add_up($a, $b){
 $arr = array(
   $a,
   $b,
   $a + $b
     );
  return $arr;
}

$value = add_up(2, 4);

echo $value[2];

?>

Instead of array{}, it's supposed to be array().
