What steps can be taken to troubleshoot "Access denied" errors when connecting to a MySQL database in PHP?

"Access denied" errors when connecting to a MySQL database in PHP typically occur due to incorrect credentials or insufficient permissions. To troubleshoot this issue, double-check the username, password, host, and database name in your connection settings. Ensure that the user has the necessary privileges to access the database. 

<?php
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$database = "your_database";

// Create connection
$conn = new mysqli($servername, $username, $password, $database);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>
