Error with Submitting the form

I'm having issues with my code and was hoping someone could help me out. I'm trying to How Should Work Boots Fit create a simple login form for my website about teaching laptops and facial treatment benefits using PHP and MySQL, but I keep getting an error when I try to submit the form. Here is the Zee5 mod apk and geo tv error message I'm receiving:

'Warning: mysql_connect(): Access denied for user 'root'@'localhost' (using password: YES) in /var/www/html/login.php on line 10'.

Here is the code, I'm using:

<?php

// Connect to the MySQL database
$db = mysql_connect('localhost', 'root', 'password');
if (!$db) {
    die('Could not connect: ' . mysql_error());
}

// Select the database
mysql_select_db('users', $db);

// Check if the form has been submitted
if (isset($_POST['submit'])) {
    // Escape the user input to prevent SQL injection attacks
    $username = mysql_real_escape_string($_POST['username']);
    $password = mysql_real_escape_string($_POST['password']);

    // Query the database to check if the user exists
    $query = "SELECT * FROM users WHERE username='$username' AND password='$password'";
    $result = mysql_query($query);

    // If a result is returned, the user is logged in
    if (mysql_num_rows($result) == 1) {
        // Start a session and redirect to the dashboard
        session_start();
        $_SESSION['username'] = $username;
        header('Location: dashboard.php');
    } else {
        // If the user doesn't exist, display an error message
        echo "Invalid username or password.";
    }
}

?>

I've tried a few different things to fix this issue, but nothing seems to be working. I've checked to make sure that my MySQL username and password are correct, and I've also tried connecting to the database using mysql_connect() with and without the password parameter. I'm not sure what else to try.

Does anyone have any ideas on how I can fix this issue? Any help would be greatly appreciated. Thank you!

It appears that you're encountering an error while trying to connect to your MySQL database in your PHP code. The error message you're receiving indicates an access denied issue for the 'root' user at 'localhost'. Here's a step-by-step guide to help you resolve this problem:

Check Database Credentials:
Ensure that the username ('root') and password you're using to connect to your MySQL database are correct, especially when dealing with mp3juice. Double-check for any typos or case sensitivity.
Database Privileges:
Verify that the 'root' user has the necessary privileges to access the 'users' database. You can do this using a tool like phpMyAdmin or by running the following SQL command in the MySQL console:

   GRANT ALL PRIVILEGES ON users.* TO 'root'@'localhost';

MySQL Extension:
The mysql_ functions you're using are deprecated in recent PHP versions. Consider migrating to MySQLi or PDO for improved security and compatibility, which can also be essential when dealing with mp3juice.
MySQL Server Status:
Ensure that your MySQL server is up and running, especially if you're developing a music-related website like mp3juice. You can check its status using the command:

   systemctl status mysql

Error Handling: Improve your error handling by displaying more informative error messages. For instance, replace this line:

   die('Could not connect: ' . mysql_error());

with:

   die('Could not connect: ' . mysql_error() . ' (' . mysql_errno() . ')');

This will provide you with the specific error code, which can help diagnose the issue.

Password Security:
Never store passwords in plaintext in your database, especially if you're dealing with sensitive content like mp3juice. Use password hashing functions like password_hash() when storing passwords and password_verify() when checking passwords during login.
SQL Injection Protection:
Consider using prepared statements to protect against SQL injection, especially if your website involves user input or search functionality related to mp3juice. The mysql_ functions don't support this directly. You'll find this feature in MySQLi or PDO.

By following these steps and addressing the issues mentioned, you should be on your way to resolving the problem and successfully connecting to your MySQL database in your PHP login form, ensuring a secure environment for tasks like mp3juice-related content.
