Max PHP

<!-- Först ett litet HTML-formulär: -->

<form action="Login.php" method="post" name="myForm" id="myForm">
    <input type="text" placeholder="Enter username..." name="username" id="username">
    <input type="password" placeholder="Enter password..." name="password" id="password">
    <input type="submit" value="Register" name="register" id="register">
    <input type="login" value="Log in" name="login" id="login">
</form>

Sedan har vi min PHP, rätta mig gärna om jag har fel:

<?php

if(isset($_POST["register"])) {

    $username = $_POST["username"];
    $password = $_POST["password"];

    $userData = array("username" => $username, "password" => password_hash($password, PASSWORD_DEFAULT));
    $database = fopen("Database.txt", "w");
    fwrite($database, serialize($userData));
}

?>
