Syntax error??

$i = 0;
foreach(htmlspecialchars($_SESSION['word']))
{
  $i++;
  if(empty $_SESSION['word']['$i'])
  {
    header("Location: play.php?p=".$i);
  }
}

How could there be a syntax error in the above code? the syntax error would persist at the for last closing braces.. hmm :/

few things i noticed.

a. in php foreach need a as value. b. if isset && !empty for the $ _session

$i = 0; 
foreach(htmlspecialchars($_SESSION['word']) as $value) {

 $i++;
 if(isset($_SESSION['word']['$i']) && !empty($_SESSION['word']['$i'])) {
    header("Location: play.php?p=".$i); 
    }
  }

hope this helps

A couple things

1) "empty" needs parenthesis

if(empty($_SESSION['word']['$i']))

2) htmlspecialchars should be used on the individual items, not the $_SESSION['word'] array.
