From a checkbox submit(post) i have an array like this. So this value will be dynamic in form submit. The variable name is $my_values.

Output

    Array
    (
        [0] => 1
        [1] => 2
        [2] => 2_6
        [3] => 3
        [4] => 3_7
        [5] => 3_8
        [6] => 4
        [7] => 4_9
        [8] => 4_10
        [9] => 4_11
        [10] => 4_12
        [11] => 4_13
        [12] => 4_13_14
        [13] => 5
    )

Expected Output

    1,2,3,4,5,6,7,8,9,10,11,12,13,14

So I need to get the output as above in a single variable. How can I achieve that?

In other words :

$my_values is having the array as i have mentioned. i want one more variable $my_results which will convert the array values and give it as a single value with comma seperator (i.e 1,2,3,4,5,6,7,8,9,10,11,12,13,14)

Thanks Kimz

if you need each id just once, you can do something like this:

$tmp = implode(',', $my_values);
$tmp = str_replace('_', ',', $tmp);
$idList = explode(',', $tmp);
$my_results = implode(',', array_unique($idList));
echo $my_results;
