What are the best practices for organizing PHP scripts to avoid confusion and errors?

To avoid confusion and errors when organizing PHP scripts, it is important to follow best practices such as using meaningful variable names, commenting code effectively, breaking down complex tasks into smaller functions, and organizing files and folders logically. 

// Example of organizing PHP scripts with best practices

// Define constants for configuration settings
define('DB_HOST', 'localhost');
define('DB_USER', 'root');
define('DB_PASS', 'password');
define('DB_NAME', 'my_database');

// Connect to the database
$connection = mysqli_connect(DB_HOST, DB_USER, DB_PASS, DB_NAME);

// Check connection
if (!$connection) {
    die("Connection failed: " . mysqli_connect_error());
}

// Perform database operations
$query = "SELECT * FROM users";
$result = mysqli_query($connection, $query);

// Process query results
if (mysqli_num_rows($result) > 0) {
    while ($row = mysqli_fetch_assoc($result)) {
        echo "User: " . $row["username"] . "<br>";
    }
} else {
    echo "No users found";
}

// Close database connection
mysqli_close($connection);
