that only works for numerical indices.

However, if you're sure that neither null values, nor false values are
supposed to be present in the array, (that means, they MIGHT be, but
should be removed anyway; or just not be there at all,) then you could
try array_filter with no callback-argument :)

Another easy way would be:
foreach($array as $key=>$val) {
if($val === '') {
unset($array[$key]);
}
}

hope it helps
