How can PHP be configured to access user credentials stored in a separate file for database connection?

To configure PHP to access user credentials stored in a separate file for database connection, you can create a separate PHP file that contains the credentials as variables. Then, include this file in your main PHP script that connects to the database. This way, you can easily update the credentials in one place without having to modify the main script. 

// credentials.php
<?php
$host = 'localhost';
$username = 'myusername';
$password = 'mypassword';
$database = 'mydatabase';
?>

// main.php
<?php
include 'credentials.php';

$conn = new mysqli($host, $username, $password, $database);

if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

echo "Connected successfully";
?>
