What are some best practices for organizing and structuring PHP code to improve maintainability?

Organizing and structuring PHP code is essential for improving maintainability. One best practice is to follow a consistent naming convention for variables, functions, and classes. Another is to separate concerns by using a modular approach, such as dividing code into separate files or using a framework like MVC. Additionally, commenting code and using meaningful documentation can help others understand the codebase more easily. 

// Example of organizing and structuring PHP code using a modular approach

// index.php
require 'functions.php';
require 'classes.php';

$myObject = new MyClass();
$myObject->doSomething();

// functions.php
function myFunction() {
  // code here
}

// classes.php
class MyClass {
  public function doSomething() {
    // code here
  }
}
