I wrote a function like that

function rm_empty_values($array) {
	$x = 0;
	foreach ($array as $key => $value) {
		if($value) {
			$array_temp[$x] = $value;
			$x++;
		}
	}
	return $array_temp;
}

$hede = array("hede", "hodo", "0", 1);
$list = rm_empty_values($hede);
print_r($list);

but it removes $hede[2] (0 value) too and i modified my function to

function rm_empty_values($array) {
	$x = 0;
	foreach ($array as $key => $value) {
		if(($value) || ($value == "0")) {
			$array_temp[$x] = $value;
			$x++;
		}
	}
	return $array_temp;
}

and it works.
