To troubleshoot issues related to establishing a connection between phpMyAdmin and the MySQL server, you can check the database credentials in the configuration file, ensure that the MySQL server is running, and verify that the connection settings in phpMyAdmin are correct.

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "mydatabase";

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

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