从PHP数组中删除空格/空值

I'm developing a word counting application and I'm using following code to load words to an array.

$str = ' Some string is here     ...  Another string.. ';
$str = trim($str);
$str = preg_replace('/\s+/', ' ', $str);
$str_array = explode(" ", $str);
$str_array = array_filter($str_array);

But the issue is I'm getting empty values in my array like follows.

Array
(
    [0] => Word1
    [1] => Word2
    [2] => Word3
    [3] => 
    [4] => 
    [5] => 
)

I've tried array_filter($str_array) and more stackoverflow answers. But I was failed to get this done. Can some one please help me to fix this issue? Thanks!

    I was able to fix this issue with $str = preg_replace('/[^(\x20-\x7F)]*/','', $str);

    Source

            $str = strip_tags($str);
            $str = trim($str);
            $str = preg_replace('/ HYPERLINK "[^"]*" /', '', $str);
            $str = preg_replace('/\s+/', ' ', $str);
            $str = preg_replace('/[^(\x20-\x7F)]*/','', $str);
