Sum from one variable to the rest left

Question

0.00/5 (No votes)

See more:

I have a code with 100 variables, which I'm thinking I must have made them arrays, even though I keep having problems with it. I'm still learning.
variables are
variable1, variable2, variabl3, and so on.
So depending on what the user submits, ,let's say 3. Gives the total from variable 4 to 100.

Thanks a lot for your time and help!

What I have tried:

I have tried making variables and making infinite "ifs" but there's gotta be a better way.

There's nothing to help with here. We know nothing about your code at all, other than the statement "I have a code with 100 variables", which makes an experienced person cringe. If you've got 100 variables for anything, you've got a MASSIVE design problem that will only be solved by scraping the code and rewriting with a better design.

Solution 1

PHP

$a = array(1, 2, 3, 4, 5 ... 98, 99, 100);
$b = array_slice($a, 3);
$c = array_sum($b);
