Answer 1

As far I have understood your question, you need to merge two arrays and have unique values in the result array.

$result = array_unique (array_merge($array1, $array2));

This will give an array with unique values merged from two given arrays.

Hi i font my ans.

    $words1= explode(" ", $string1);
    $words2= explode(" ", $string2);
    $result = array_intersect($words1, $words2);
     
    
    $clean1 = array();
    $array_a = $words2; // assume this is your first array
    $array_b = $result; // assume this is the array you wan to compare against
    $found = false;
    
    foreach ($array_a as $key_a => $val_a) {
        $found = false;
        foreach ($array_b as $key_b => $val_b) {
           if ($val_a == $val_b) {
                   $clean1[$key_b] = $val_b;
                    break;
                   $found = true;
            }     
        }
        if (!$found){}
    }
    return count($clean1);
