I have an array looking like this:

PHP Code:
Array
(
    [
0] => 1,g,10,97
    
[1] => 2,j,0,106
    
[2] => 3,b,3,32
    
[3] => 4,b,9,44
    
[4] => 5,r,11,21
    
[5] => 6,y,7,66
    
[6] => 7,y,1,54
    
[7] => 8,b,4,33
    
[8] => 15,y,12,75
    
[9] => 16,g,7,92
    
[10] => 17,y,3,58
    
[11] => 18,b,8,41
    
[12] => 19,b,13,51
    
[13] => 20,r,5,9
    
[14] => 21,g,5,88
    
[15] => 22,y,4,59

Now, I only want add the numbers after the second comma in each record together... How do I do so?

Please help and thanks in advance :-)
