Question

i have two array and i want to make unique array with single array

for example i have $a=array(3); and $b=array(1,2,3) so i want $c=array(1,2,3)

i made a code like:

            $a=array(3);
        $b=explode(',','1,2,3');
        $ab=$a+$b;
        $c=array_unique ($ab);
            print_r($c);

it gives me Array ( [0] => 3 [1] => 2 )

but i want to Array ( [0] => 1 [1] => 2 [2] => 3 )

Answer 1

$a = array(1,2,3,4,5,6);

$b = array(6,7,8,2,3);

$c = array_merge($a, $b);

$c = array_unique($c);
