What are the best practices for organizing PHP code within a project?

Organizing PHP code within a project is essential for maintaining readability, scalability, and maintainability. One common practice is to use a modular approach by separating code into different files or directories based on functionality. This can include creating separate files for functions, classes, configuration settings, and templates. Additionally, following naming conventions, using meaningful variable and function names, and commenting code can also help improve organization. 

// Example of organizing PHP code within a project

// functions.php
function calculate_sum($a, $b) {
    return $a + $b;
}

// classes/Calculator.php
class Calculator {
    public function multiply($a, $b) {
        return $a * $b;
    }
}

// config.php
define('DB_HOST', 'localhost');
define('DB_USER', 'root');
define('DB_PASS', 'password');

// templates/header.php
<html>
<head>
    <title>Project Title</title>
</head>
<body>
