If I want to add several values together with BCMath I could do like this:
$total_cost1 = bcadd($value1, $value2);
$total_cost2 = bcadd($value3, $value4);
$total_cost3 = bcadd($value5, $value6);
$total_cost4 = bcadd($value7, $value8);
$total_cost =
bcadd(bcadd($total1_cost, $total2_cost),
bcadd($total3_cost, $total4_cost));
but it makes it so unreadable and it would be easy to make mistakes. Please tell me there is a another way of solving this...!?
There's nothing wrong with that approach, just hide it.
You can write a generic function which takes an array of numbers and adds them in a loop.
Then you can simply: bcsum(array($value1, $value2, ....))
