What best practices should PHP developers follow when structuring and organizing their code to avoid confusion and improve readability?

PHP developers should follow best practices such as using meaningful variable and function names, organizing code into logical sections, commenting code effectively, and following a consistent coding style. By structuring and organizing their code in a clear and readable manner, developers can avoid confusion and make it easier for themselves and others to understand and maintain the code. 

<?php

// Example of well-structured and organized PHP code

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

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

// Check if the connection was successful
if ($connection->connect_error) {
    die("Connection failed: " . $connection->connect_error);
}

// Query the database
$query = "SELECT * FROM users";
$result = $connection->query($query);

// Loop through the results
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        echo "Name: " . $row['name'] . "<br>";
    }
} else {
    echo "No results found";
}

// Close the database connection
$connection->close();

?>
