Without actually running it (I'm too lazy!), I'm pretty sure this won't work
correctly -- the count($array) is being recalculated each time round the
loop, so each time you do an unset() it will reduce by one, resulting in the
last few elements never being checked.

It should, however, be perfectly possible to use foreach in the same way:

foreach ($array as $i=>$value) {
if (empty($value]) {
unset($array[$i]);
}
}

Cheers!
