It'd be similar to checking if an account exists in database, there's a common example for you. Except your checking phone number row not names row. If it does exist then you can generate another random number. Even could be recursive if you call the function again at this point but it'd require 10 lottery luck to make the same number on two rng. Unless you already have 50k characters and do no cleanup on inactive ones and don't improve the script by then

I recommend you edit a current mySQL gamemode rather than write your own shit if this is your current level
