I'm only getting the latest price not the total price. The product_price in other table which is product. I'm trying to get total price from cart table. PHP arraysum() function can find sum of both indexed arrays and associative arrays. number arraysum ( array ) Argument The only argument to the function is the array whose sum needs to be calculated.
