What are some best practices for organizing PHP code in an editor?

When organizing PHP code in an editor, it is important to follow best practices to improve readability and maintainability. One common approach is to separate code into logical sections using comments or whitespace. Another helpful practice is to use proper indentation and consistent naming conventions for variables, functions, and classes. Additionally, grouping related functions or classes together can make it easier to navigate and understand the code.

<?php

// Section 1: Constants
define('PI', 3.14);

// Section 2: Functions
function calculateArea($radius) {
    return PI * $radius * $radius;
}

// Section 3: Classes
class Circle {
    private $radius;

    public function __construct($radius) {
        $this->radius = $radius;
    }

    public function getArea() {
        return PI * $this->radius * $this->radius;
    }
}

?>
