How do I get the last index of string.split()?
Lets say i have this string “1/2/3/4/5” and i split at the / how do i get the last index (in this case 5)?
Ive looked around the DevForum but found nothing that helped me.

You can do string.split("1/2/3/4/5","/")[#string.split("1/2/3/4/5","/")]

ok thanks but I just realized that i need the index before that so (4) and not the last one

#4

string.split returns an array of all the split strings so you can just index whichever element directly if it doesn’t change (arr[4]) or iterate the array and find the index that contains “4”

local numbers = string.split("1/2/3/4/5", "/")

local four = numbers[4]

print(four) --> 4

yes i know that but the string that im trying to split changes in length

#6

i tryed to loop through the array and then remove 1 and print that but that just gives me nil

#7

I don’t understand what you’re trying to do, you want to get the second last index of an array?

#8

You can do string.split("1/2/3/4/5","/")[#string.split("1/2/3/4/5","/")-1] instead

that just gives me a error
attempt to perform arithmetic (sub) on string and number

My bad, i edited the reply. Maybe that will work

#11

Then you can just do

string.split("1/2/3/4/5","/")[#string.split("1/2/3/4/5","/")-1] -- subtract 1 from table length

(whoops, didn’t realise someone already gave the exact same solution)
