Answer 1

A solution would be to split your strings into two arrays of words -- using explode(), for instance :

$string1 = "Product Name - Blue";
$string2 = "Blue Green Pink Black Orange";

$arr1 = explode(' ', $string1);
$arr2 = explode(' ', $string2);

Note that explode() is a basic solution ; you might want to use something a bit more complex, like preg_split(), which allows for more specific delimiters.

And, then, to use array_intersect() on those arrays, to find out which words are present in both :

$common = array_intersect($arr1, $arr2);
var_dump($common);

Which, in this case, would give :

array
  3 => string 'Blue' (length=4)
