$items = explode(',',$product); // values is 4,2,4,2,2,4 $unique_items=array_unique($items); // gives me 4,2 What code should be next to give me 4 = 3 , 2 = 3 and store the number of values to a variable?

To count the duplicates in an array: Declare an empty object variable that will store the count for each value. Use the forEach() method to iterate over the array. On each iteration, increment the count for the value by 1 or initialize it to 1 .

Yes, you do.
see: array_count_values
Like:
$occurences = array_count_values($items); print_r($occurences); Output:
Array ( [4] => 3 [2] => 3 ) Usage:
echo $occurences[4]; // outputs 3 You're probably looking for array_count_values() function.
