Do one thing, Use print_r() instead of var_dump(). And copy result in your question... — Hardik Solanki

Try array_filter()

$a = [null,'h',null,'g'];
echo '<pre>';
print_r(array_filter($a ,function($a){
        if($a !== null)
            return $a;
    }));

The array_unique(array) removes duplicate entries, then remove single null

Try;

$array = array_unique($array);
if(($key = array_search("null", $array)) !== false) {
    unset($array[$key]);
}

Just Use array_filter() See more here

Code :

$new_Array=array_filter($old_Array);
print_r($new_Array);

<?php
$arr=array("null","null","Federal Bank (India) - Banking","null","null","Federal Bank (India) - Banking");
$str=implode(' ',$arr);
echo $str."<br>";
echo$new_str=str_replace("null","",$str);// replace all null and your expected output
