I'm trying to figure out how am I supposed to write this snippet

  if (($index = array_search($search, array_keys($pages))) !== false) {
    echo "index: $index\n";
  } else {
    echo "Not found\n";

 When I search for something that I know exists, it returns the $index
just fine.  However, when I search for something that does not exist, it
never tells me 'Not found', instead it just displays a blank index (it
looks like $index = "", not false).  Should I be checking it against
'false', or against "" ?

    Using PHP 4.0.7-dev.

W | I haven't lost my mind; it's backed up on tape somewhere.
