woops, the echo tags have a ‘pre’ tag in them.

  For beginners:
  The reason we use a comma instead of a period/dot between the ‘pre’ and the print_r() is because print_r() does an echo from itself.
  If you would use a dot instead then it PHP will echo print_r() and AFTER that a pre and a /pre.

  PS:
  As we can read here:
  http://nl3.php.net/manual/function.print-r.php
  print_r() takes a second argument to return instead of echo:
```
echo '<pre>' . print_r($array,true) . '</pre>';
```
  Note: We use dots instead of comma’s, and give print_r() an extra ‘true’ (= return).
  Not as short, but just to explain to beginners how the spoon fits in the fork xD
