[PHP] Nested for() loops?

[jvoth]

Howdy Y'all!

I'm trying to figure out why I'm having so much difficulty with
nested for loops.

As a test, I did this and it doesn't work. The script simply doesn't 
give any output.

<?
 error_reporting(E_ALL);

 for( $i=0; $i<10; $i++ )
  for( $j=0; $j<10; $j++ )
  {
    $res = $i * $j;
    print(" result = $res <br>");
  }
?>

If I remove the inner loop then it works fine but that's useless.

I am hoping to figure out how to make this work since I need to 
populate a 2 dimensional array with results from multiple database
queries.

Any ideas? Anything obviously wrong?

Thanks in advance!
John
