    SOLVED - After a long diagnose and look through I got to fix the problem.

    ----------------------------------------------------------------------------------------------

    Hello and welcome fellow coders I have an intense problem I can't seem to shake on my own.

    I am currently coding a Web API for my server and want the server to send the players trimmed UUID and the type of action I want it to go to to handle the UUID.

    The problem with my code is during connection I get a 400 Bad Request page when I print my data on my "PlayerLoginEvent":

    $data = get($_POST["uuid"]);
    echo(    json_encode($data != null ? $data : array()));
    My other files such as add and remove are similar to the Get file so I wont add them in.

    Heres what I get back when I print it in console the data I recieve from the server:
    Console Message (open)

    I tried pretty much everything when it comes to obvious choices, I checked the heck out of google, I looked on Stack Overflow to see if anyone had similar problems, I checked Bukkit Forums (I didn't expect anything I just did.), I even quadruple checked my code but I couldn't see anything wrong with it.

    I apologize if this isn't the place to go for this type of problem. (I'm new to Bukkit Forums... well forums in general)

    Wouldn't it be easier to connect to the SQL database directly through Java? Having to pass through PHP all the time just seems like a hassle.

    You're right. I never knew about that. I was following a video and just saw what he did. I never knew you can connect directly.

    Do you happen to know how to connect directly to a MySQL Database?

    I'm no expert, but you should be able to use the MySQL driver that's shaded into bukkit. Something like this:
    Code:java
    1. try {
    2.     // This initializes the jdbc Driver and makes it do all its magic to register itself.
    3.     Class.forName("com.mysql.jdbc.Driver");
    4.     Connection connection = DriverManager.getConnection("jdbc:mysql://<address of your MySQL database>", "MyUsername", "MyPassword");
    5. } catch (ClassNotFoundException | SQLException e) {
    6.     e.printStackTrace();
    7. }
