you guys are all full of bullshit. you
JUST need the php file website to be hosted on the computer where the server is being handled(Ex: Server status, player count etc)
I dont know much but I do know that just assign 3 values(strings)
Code:
$account;
$password;
$newpassword;
assign $password to whatever they putin to be there real password and $newpassword as what they want there new password to be and $account to there account
Simply just try and validate there account exists
Code:
#The code that checks if a file exists
if the value is true open the file and see if it contains the string ($password) if it does then replace it with the new password if not then the password is wrong.
That's probably not the most efficient way to do it but it will work.
