Answer 1

You can use array_filter to remove empty value (null, false,'',0):

array_filter($array);

If you don't want to remove 0 from your array, see @Sabari's answer:

array_filter($array,'strlen');

Answer 2

You can use:

To Remove NULL values only:

$new_array_without_nulls = array_filter($array_with_nulls, 'strlen');

To Remove False Values:

$new_array_without_nulls = array_filter($array_with_nulls);

Hope this helps :)

Answer 3

array_filter($array, function($var) {
    //because you didn't define what is the empty value, I leave it to you
    return !is_empty($var);
});
