In Codeigniter view file adding php string values the simplest way

I'm trying to add up these values within this string. I tried "array_sum" but it made the entire page show blank. I also tried "explode" but it still just showed the same values.

DATA TABLE

goal_af_am_msm | goal_year |      77              2020     0               2020     3500            2020     406             2020     60              2020     1               2020     155             2020     150             2020     130             2020     125             2020     77              2020     271             2020     1               2020     0               2020     1               2020     102             2020     102             2020     250             2020     146             2020     77              2020     204             2020     1               2020     5               2021     78              2021     23              2021     87              2021     12              2021     76              2021
