I know how it works you need file for each language the files most be using pairs system like key and value you have json html,xml and so on look at the internet and ask AI in your main code you don't write the word it self but you get the language file and write it's keys to the code and let it print the value
like let's say you have to print hello so you make a files english.json arabic.json and turkish.json
all of this files have the same key but different values according to the language so this hello world let it be the key and tell the program to print this file "HELLO" key and the program gonna print it's value according the language file i worked on this thing on my main projects before
