What steps can be taken to resolve the issue of not being allowed to connect to a MySQL server in PHP?

The issue of not being allowed to connect to a MySQL server in PHP can be resolved by checking the credentials used for connecting to the MySQL server, ensuring that the user has the necessary permissions to access the database, and verifying that the MySQL server is running and accessible from the PHP server. 

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

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

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