Answer 1

To get unique values from array use array_unique():

$array = array(1,2,1,5,10,5,10,7,9,1) ;
array_unique($array);
print_r(array_unique($array));

Output:

Array
(
    [0] => 1
    [1] => 2
    [3] => 5
    [4] => 10
    [7] => 7
    [8] => 9
)

And to get duplicated values in array use array_count_values():

$array = array(1,2,1,5,10,5,10,7,9,1) ;
print_r(array_count_values($array));

Output:

Array
(
    [1] => 3 // 1 is duplicated value as it occurrence is 3 times
    [2] => 1
    [5] => 2 // 5 is duplicated value as it occurrence is 3 times
    [10] => 2 // 10 is duplicated value as it occurrence is 3 times
    [7] => 1
    [9] => 1
)
