Compare only values of arrays and get difference

manpreet Best Answer 2 years ago

I have two arrays like below;

array1 =  {
           [0]=> 'A'
           [1]=> 'B'
           [2]=> 'C'
          }

array2 =  {
           [0]=> 'B'
           [1]=> 'C'
           [2]=> 'D'
          }

I want to compare these two arrays and get the difference.
What I need return is like this;

result =  {
            [0]=> 'A'
            [1]=> 'D'
           }
I thought I could use array_diff, but it compares key AND value as a pair. I want to compare ONLY values. How can I do that?

array_diff(array_merge($a, $b), array_intersect($a, $b))
