How can PHP scripts be structured to prevent users from having to directly edit them for database connection details?

To prevent users from having to directly edit PHP scripts for database connection details, you can store the database connection details in a separate configuration file outside of the web root directory. This way, users cannot access the file directly through a URL. Then, include this configuration file in your PHP scripts to establish the database connection. 

// config.php
<?php
$db_host = 'localhost';
$db_user = 'username';
$db_password = 'password';
$db_name = 'database';

// database.php
<?php
include 'config.php';

$conn = new mysqli($db_host, $db_user, $db_password, $db_name);

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